Directories touched: evaporation (everywhere), handler (MAC's changes + JMQ 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) G4StatMFMacroTemperature - return original algorithm G4StatMFMacroMultiplicity - additional checks in solver of equation for the chemical potential G4StatMFMacroCanonical - fixed infinite loop for a fagment with Z=A; fixed memory leak G4StatMFChannel - fixed semi-infine loop G4StatMFMacroMultiNucleon - fixed computation of the symmetry energy 24 July 2008 V.Ivanchenko (hadr-deex-V09-01-11) --------------------------------------------------- G4EvaporationProbability - Coulomb barrier upgraded (J. M. Quesada) 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.

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. 24 Nov 2005 Dennis Wright (hadr-deex-V07-01-00) ---------------------------------------------- - photon_evaporation (tag hadr-deex-photo-V07-01-00 by Aatos Heikkinen) migration for G4NuclearLevelManager.cc, G4NuclearLevelDataStore.cc, G4DiscreteGammaDeexcitation.cc minor update of G4VGammaDeexcitation.cc - util (tag hadr-deex-util-V07-01-00 by Aatos Heikkinen) migration for G4CoulombBarrier.cc G4VCoulombBarrier.cc, - gem_evaporation (tag hadr-deex-gem-V07-01-00 by Aatos Heikkinen) migration for G4GEMCoulombBarrierHE.cc - fermi_breakup (tag hadr-deex-fermi-V07-01-00 by Aatos Heikkinen) migration for G4FermiSplitter.cc
