428Directories touched: evaporation (everywhere), handler (MAC's changes + JMQ
429interface changes), management (G4VEvaporationChannel.hh (interface)), util
430(G4VEmissionProbability.hh (interface)) - MIS-TAGGED - this is closer to ref07

451
45212 July 2008 V.Ivanchenko (hadr-deex-V09-01-10)
453---------------------------------------------------
454Integraded fixes in G4EvaporationProbabilities and the tag hadr-deex-V09-01-08,
455OPT=2 is set (J. M. Quesada)
456
45705 June 2008 A.Howard (hadr-deex-V09-01-09)
458---------------------------------------------------
459
460Fixed memory leak in G4ExcitationHandler thanks to Tatsumi Koi.  The fix is on
461top of hadr-deex-V09-01-01, but does not include any of the other subsequent
462developments.  Required for public beta release.
463
46405 June 2008 J. M. Quesada (hadr-deex-V09-01-08)
465---------------------------------------------------
466
467 Bug fixed in OPT=1 (Chatterjee) charged particle cross sections.
468Unphysical values at very low emission energies have been corrected (set
469to 0).
470OPT=1 by default ( OPT=2 in previous tag)
471
472
473 24 May 2008 A.Howard (hadr-deex-V09-01-07)
474---------------------------------------------------
475
476As hadr-deex-V09-01-06 but with photon_evaporation updated to new interface.
477Should now be stable (co-works with low energy tag emlowen-V09-01-14, I guess) -
478see hadr-deex-V09-01-01.
479
480 24 May 2008 A.Howard (hadr-deex-V09-01-06)
481---------------------------------------------------
482
483As hadr-deex-V09-01-05 but with G4ExcitationHandler.cc put back to correct version
484
485
486 24 May 2008 A.Howard (hadr-deex-V09-01-05)
487---------------------------------------------------
488
489Updated to Jose Manuel Quesada's latest version (should be what was intended in
490hadr-deex-V09-01-03).  Does not include Fan Lei's interface change. This is,
491however, still on the HEAD.
492
493 24 May 2008 A.Howard (hadr-deex-V09-01-04)
494---------------------------------------------------
495
496Updated to Jose Manuel Quesada's latest version (should be what was intended in hadr-deex-V09-01-03).  Also includes Fan Lei's change
497to the photon_evaporation interface.
498

500 08 May 2008 J. M. Quesada (hadr-deex-V09-01-03)
501---------------------------------------------------
502
503 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.   
504
505 01 May 2008 J. M. Quesada (hadr-deex-V09-01-02)
506---------------------------------------------------
507- First trial with cvs.
508New inverse cross sections:
509        OPT=1 Chetterjee's parameterization to reaction cross sections from optical potential global fittings.
510        OPT=2 as OPT=1 but for protons the Wellisch's parameterization for protons is used  (DEFAULT)
511        OPT=3 Kalbach's modifications of Chatterjee's parameterization of cross sections
512        OPT=4 as OPT=3 but for protons the Wellisch's parameterization for protons is used
513
514Coulomb 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. 
515
516
517 01 May 2008 Fan Lei (hadr-deex-V09-01-01)
518---------------------------------------------------
519- photon_evaporation
520  G4PhotonEvaporation.cc: Atomic relaxation model is no longer applied following
521  internal electron conversion. Instead the vaccant shell index is passed to
522  radioactive decay model, where the ARM is applied. 
523
524 21 March 2008 Dennis Wright (hadr-deex-V09-01-00)
525--------------------------------------------------
526- added parentheses to fix gcc-4.3 compiler warnings in
527  G4StatMFChannel::CheckFragments and ::PlaceFragments
528
529 15 November 2007 Alex Howard (hadr-deex-V09-00-06)
530---------------------------------------------------
531- Added Jose Manuel Quesada's modification to util/src/G4CoulombBarrier.cc in
532  order to go back to the original Dostrovski's formulation which is described
533  in the Physics Reference Manual.  The previous implementation (from Vicente
534  Lara) was inconsistent and less to an under-estimate of the Coulomb Barrier.
535
536
537 15 November 2007 F Lei (hadr-deex-V09-00-05)
538---------------------------------------------------

543
544
545 01 November 2007 Dennis Wright (hadr-deex-V09-00-04)
546-----------------------------------------------------
547- suppressed gamma level file warnings in G4NuclearLevelManager.cc

550 
551
552 01 October 2007 Alex Howard (hadr-deex-V09-00-03)
553---------------------------------------------------

567
568 23 August 2007 Alex Howard (hadr-deex-V09-00-01)
569-----------------------------------------------
570- Removed Coulomb Barrier to beta parameter as it's already included in the
571  inverse cross-section formula and is introduced in terms of the energy limit
572  of the integration.
573- Introduced missing Rj factor in the following files (evaporation module):
574  G4EvaporationProbability.cc, G4EvaporationProbability.hh,
575  G4AlphaEvaporationProbability.hh, G4DeuteronEvaporationProbability.hh,
576  G4He3EvaporationProbability.hh, G4NeutronEvaporationProbability.hh,

581-----------------------------------------------
582- Added Coulomb Barrier to Beta parameter for inverse channel
583cross-section. Needs verification.  Required additions and changes to the
584following files:
585G4EvaporationProbability.hh, G4EvaporationProbability.cc,
586G4AlphaEvaporationProbability.hh, G4DeuteronEvaporationProbability.hh,
587G4He3EvaporationProbability.hh, G4NeutronEvaporationProbability.hh,

595-----------------------------------------------
596- Fixed bug in fix "hadr-deex-V08-03-00" - deleted pointers and iterators were
597  attempted to be accessed.  Now a final state iterator list is created and
598  filled when necessary.
599
600
601 18 May 2007 Alex Howard (hadr-deex-V08-03-00)
602-----------------------------------------------
603- Fixed bug in low A,Z false condition in G4DiscreteGammaDeexcitation.cc, now
604the condition is (Z<2 || A<3 || Z>98) false (so stops at Cf rather than >100)
605and includes helium (previously excluded)
606- Fixed bug in pointer to iterator moving before its beginning G4ExcitationHandler.cc
607
608 14 Feb 2007 Alex Howard (hadr-deex-V08-02-02)
609-----------------------------------------------
610- evaporation
611   Added protection to exclude negative probabilities from the
612   "competitive channel sum". With fix below this should only happen due to
613   a precision error, but is protected nonetheless.
614
615 12 Feb 2007 Alex Howard (hadr-deex-V08-02-01)
616-----------------------------------------------
617- fission
618   Fixed probability to no longer be negative. Is now equivalent to what is
619   written in the Physics Reference Manual. Vicente Lara suggested/agreed
620   with fix.
621
622 5 Jan 2007 Dennis Wright (hadr-deex-V08-02-00)
623-----------------------------------------------
624- fission
625   Fixed several memory leaks in G4ParaFissionModel
626
62719 Aug 2006 Dennis Wright (hadr-deex-V08-01-00)
628-----------------------------------------------
629- multifragmentation
630   G4VStatMFMacroCluster.hh : removed meaningless const qualifier from
631   methods GetInvLevelDensity, GetZARatio and GetSize
632 
633- handler
634   G4ExcitationHandler.hh : removed meaningless const qualifier from
635   mehtods GetMaxZ, GetMaxA and GetMinE
636
63720 Apr 2006 Dennis Wright (hadr-deex-V08-00-03)
638-----------------------------------------------
639- photon_evaporation
640   G4NuclearLevelManager.cc : in method MakeLevels(), restrict the missing
641       file warning to Z > 10
642
64308 Apr 2006 Dennis Wright (hadr-deex-V08-00-02)
644----------------------------------------------
645- photon_evaporation
646  G4PhotonEvaporation.cc : in method BreakItUp(), fix memory leak -
647       delete entries to armProducts vector.  This is in response to
648       bug report 851.
649
65005 Jan 2006 Dennis Wright (hadr-deex-V08-00-01)
651----------------------------------------------
652
653- photon_evaporation
654   G4NuclearLevelManager.cc : in method MakeLevels(), re-enable the
655       warning that no gamma levels file exists. This is in response
656       to bug report 814.
657
658- fission
659   G4ParaFissionModel.hh : fix compilation errors which do not show up
660       because there is no .cc file.  This is in response to bug report
661       817.  Note: splitting this class into header and implementation
662       files will have to wait for a directory re-organization because
663       as it stands now, there are circular dependencies between the
664       fission and evaporation directories.
