interface changes), management (G4VEvaporationChannel.hh (interface)), util
(G4VEmissionProbability.hh (interface)) - MIS-TAGGED - this is closer to ref07
***********PLEASE IGNORE**********


25 July 2008 V.Ivanchenko (hadr-deex-V09-01-12)
---------------------------------------------------
Multi-Fragmentation model have been fixed by I.Pshenichnov in collaboration 
with Alexander Botvina and Igor Mishustin (FIAS, Frankfurt, INR,
Moscow and Kurchatov Institute, Moscow, pshenich@fias.uni-frankfurt.de)

12 July 2008 V.Ivanchenko (hadr-deex-V09-01-10)
---------------------------------------------------
Integraded fixes in G4EvaporationProbabilities and the tag hadr-deex-V09-01-08,
OPT=2 is set (J. M. Quesada)

05 June 2008 A.Howard (hadr-deex-V09-01-09)
---------------------------------------------------

Fixed memory leak in G4ExcitationHandler thanks to Tatsumi Koi.  The fix is on
top of hadr-deex-V09-01-01, but does not include any of the other subsequent
developments.  Required for public beta release.

05 June 2008 J. M. Quesada (hadr-deex-V09-01-08)
---------------------------------------------------

 Bug fixed in OPT=1 (Chatterjee) charged particle cross sections. 
Unphysical values at very low emission energies have been corrected (set 
to 0).
OPT=1 by default ( OPT=2 in previous tag)


 24 May 2008 A.Howard (hadr-deex-V09-01-07) 
---------------------------------------------------

As hadr-deex-V09-01-06 but with photon_evaporation updated to new interface.
Should now be stable (co-works with low energy tag emlowen-V09-01-14, I guess) - 
see hadr-deex-V09-01-01.

 24 May 2008 A.Howard (hadr-deex-V09-01-06) 
---------------------------------------------------

As hadr-deex-V09-01-05 but with G4ExcitationHandler.cc put back to correct version


 24 May 2008 A.Howard (hadr-deex-V09-01-05) 
---------------------------------------------------

Updated to Jose Manuel Quesada's latest version (should be what was intended in
hadr-deex-V09-01-03).  Does not include Fan Lei's interface change. This is,
however, still on the HEAD.

 24 May 2008 A.Howard (hadr-deex-V09-01-04) 
---------------------------------------------------

Updated to Jose Manuel Quesada's latest version (should be what was intended in hadr-deex-V09-01-03).  Also includes Fan Lei's change
to the photon_evaporation interface.


 08 May 2008 J. M. Quesada (hadr-deex-V09-01-03) 
---------------------------------------------------

 Coulomb barrier has been added again. Standard parameterization is used for it. It acts as an additional component of inverse reaction cross sections, making it cero when emission energy drops below it. Physical reason:  reaction cross sections come from fitting to exp. data at energies normally well above the barrier. The strong competition betwen the different channels makes it very sensible to subtle differences in emission probabilities at low emission energies, when little excitation energy is available.   

 01 May 2008 J. M. Quesada (hadr-deex-V09-01-02) 
---------------------------------------------------
- First trial with cvs. 
New inverse cross sections:
        OPT=1 Chetterjee's parameterization to reaction cross sections from optical potential global fittings.
        OPT=2 as OPT=1 but for protons the Wellisch's parameterization for protons is used  (DEFAULT)
        OPT=3 Kalbach's modifications of Chatterjee's parameterization of cross sections
        OPT=4 as OPT=3 but for protons the Wellisch's parameterization for protons is used

Coulomb barrier has been suppressed as it enters through inverse cross sections. Also methods related to former Dostrovski's cross sections (alpha , beta and C parameters) have been suppressed.  


 01 May 2008 Fan Lei (hadr-deex-V09-01-01) 
---------------------------------------------------
- photon_evaporation
  G4PhotonEvaporation.cc: Atomic relaxation model is no longer applied following
  internal electron conversion. Instead the vaccant shell index is passed to 
  radioactive decay model, where the ARM is applied.  

 21 March 2008 Dennis Wright (hadr-deex-V09-01-00)
--------------------------------------------------
- added parentheses to fix gcc-4.3 compiler warnings in
  G4StatMFChannel::CheckFragments and ::PlaceFragments

 15 November 2007 Alex Howard (hadr-deex-V09-00-06)
---------------------------------------------------
- Added Jose Manuel Quesada's modification to util/src/G4CoulombBarrier.cc in
  order to go back to the original Dostrovski's formulation which is described
  in the Physics Reference Manual.  The previous implementation (from Vicente
  Lara) was inconsistent and less to an under-estimate of the Coulomb Barrier.


 15 November 2007 F Lei (hadr-deex-V09-00-05)
---------------------------------------------------
- photon_evaporation
  bug fix #952. Changes to G4VGammaDeexciation.cc:line 279; 
			G4NuclearLevelManageer.cc:line 189;
			G4ContinuumGammaDeexcitation.cc:line133.  


 01 November 2007 Dennis Wright (hadr-deex-V09-00-04)
-----------------------------------------------------
- suppressed gamma level file warnings in G4NuclearLevelManager.cc
  To turn them on again, set pre-compiler flag 
  CPPFLAGS += -DGAMMAFILEWARNING
 

 01 October 2007 Alex Howard (hadr-deex-V09-00-03)
---------------------------------------------------
- Protected Rj (Q_beta) factor against divide by zeroes - occurs occasionally.
  Following files were altered:
  G4AlphaEvaporationProbability.hh, G4He3EvaporationProbability.hh, 
  G4DeuteronEvaporationProbability.hh, G4NeutronEvaporationProbability.hh, 
  G4TritonEvaporationProbability.hh, G4ProtonEvaporationProbability.hh


 19 September 2007 Alex Howard (hadr-deex-V09-00-02)
---------------------------------------------------
- Removed atomic mass number from "gamma factor" within 
  G4DeuteronEvaporationProbability.cc, G4TritonEvaporationProbability.cc, 
  G4He3EvaporationProbability.cc, G4AlphaEvaporationProbability.cc


 23 August 2007 Alex Howard (hadr-deex-V09-00-01)
-----------------------------------------------
- Removed Coulomb Barrier to beta parameter as it's already included in the
  inverse cross-section formula and is introduced in terms of the energy limit
  of the integration.
- Introduced missing Rj factor in the following files (evaporation module):
  G4EvaporationProbability.cc, G4EvaporationProbability.hh, 
  G4AlphaEvaporationProbability.hh, G4DeuteronEvaporationProbability.hh, 
  G4He3EvaporationProbability.hh, G4NeutronEvaporationProbability.hh, 
  G4ProtonEvaporationProbability.hh, G4TritonEvaporationProbability.hh


 28 July 2007 Alex Howard (hadr-deex-V09-00-00)
-----------------------------------------------
- Added Coulomb Barrier to Beta parameter for inverse channel
cross-section. Needs verification.  Required additions and changes to the
following files:
G4EvaporationProbability.hh, G4EvaporationProbability.cc, 
G4AlphaEvaporationProbability.hh, G4DeuteronEvaporationProbability.hh, 
G4He3EvaporationProbability.hh, G4NeutronEvaporationProbability.hh, 
G4ProtonEvaporationProbability.hh, G4TritonEvaporationProbability.hh, 
G4AlphaEvaporationProbability.cc, G4DeuteronEvaporationProbability.cc, 
G4He3EvaporationProbability.cc, G4NeutronEvaporationProbability.cc, 
G4ProtonEvaporationProbability.cc, G4TritonEvaporationProbability.cc


 5 June 2007 Alex Howard (hadr-deex-V08-03-01)
-----------------------------------------------
- Fixed bug in fix "hadr-deex-V08-03-00" - deleted pointers and iterators were
  attempted to be accessed.  Now a final state iterator list is created and
  filled when necessary.


 18 May 2007 Alex Howard (hadr-deex-V08-03-00)
-----------------------------------------------
- Fixed bug in low A,Z false condition in G4DiscreteGammaDeexcitation.cc, now
the condition is (Z<2 || A<3 || Z>98) false (so stops at Cf rather than >100)
and includes helium (previously excluded)
- Fixed bug in pointer to iterator moving before its beginning G4ExcitationHandler.cc

 14 Feb 2007 Alex Howard (hadr-deex-V08-02-02)
-----------------------------------------------
- evaporation
   Added protection to exclude negative probabilities from the 
   "competitive channel sum". With fix below this should only happen due to
   a precision error, but is protected nonetheless.

 12 Feb 2007 Alex Howard (hadr-deex-V08-02-01)
-----------------------------------------------
- fission
   Fixed probability to no longer be negative. Is now equivalent to what is
   written in the Physics Reference Manual. Vicente Lara suggested/agreed 
   with fix.

 5 Jan 2007 Dennis Wright (hadr-deex-V08-02-00)
-----------------------------------------------
- fission
   Fixed several memory leaks in G4ParaFissionModel

19 Aug 2006 Dennis Wright (hadr-deex-V08-01-00)
-----------------------------------------------
- multifragmentation
   G4VStatMFMacroCluster.hh : removed meaningless const qualifier from
   methods GetInvLevelDensity, GetZARatio and GetSize
 
- handler
   G4ExcitationHandler.hh : removed meaningless const qualifier from
   mehtods GetMaxZ, GetMaxA and GetMinE

20 Apr 2006 Dennis Wright (hadr-deex-V08-00-03)
-----------------------------------------------
- photon_evaporation
   G4NuclearLevelManager.cc : in method MakeLevels(), restrict the missing
       file warning to Z > 10

08 Apr 2006 Dennis Wright (hadr-deex-V08-00-02)
----------------------------------------------
- photon_evaporation
  G4PhotonEvaporation.cc : in method BreakItUp(), fix memory leak -
       delete entries to armProducts vector.  This is in response to
       bug report 851. 

05 Jan 2006 Dennis Wright (hadr-deex-V08-00-01)
----------------------------------------------

- photon_evaporation
   G4NuclearLevelManager.cc : in method MakeLevels(), re-enable the 
       warning that no gamma levels file exists. This is in response 
       to bug report 814. 

- fission
   G4ParaFissionModel.hh : fix compilation errors which do not show up
       because there is no .cc file.  This is in response to bug report 
       817.  Note: splitting this class into header and implementation 
       files will have to wait for a directory re-organization because 
       as it stands now, there are circular dependencies between the 
       fission and evaporation directories.
