---------------------------------------------------
|
||||
Added protection for close to zero excitation energy in
|
||||
G4PreCompoundModel.cc (according to JMQ, MAC) to not try to de-excite.

|
||||
---------------------------------------------------
|
||||
Added protection for close to zero excitation energy in
|
||||
G4PreCompoundTransitions.cc (returns 0.0), prevents FPE later on.
|
||||
|
||||
27-November 2008 A.Howard hadr-pre-V09-01-13
|
||||
---------------------------------------------------
|
||||
Added data member initialisation to G4VPreCompoundTransitions.hh
|

|

---------------------------------------------------
|

JMQ fix to G4PreCompoundNeutron.cc for Zirconium (if (nu < 0.)nu=-nu).
|

|

30-September 2008 A.Howard hadr-pre-V09-01-11

---------------------------------------------------
|

Trivial protection against negative probabilities for incident protons on
|
||||
targets with A < Carbon.
|
||||
|
||||
22-September 2008 A.Howard hadr-pre-V09-01-10
|
||||
---------------------------------------------------
|
||||
JMQ's latest developments - which are an extension of hadr-pre-V09-01-08 with
|
||||
cross-section options (equivalent to the de-excitation modifications) and other
|
||||
options (SICB, Never Go Back,...). In addition Gunter's fix to the factorials
|
||||
is included from hadr-pre-V09-01-09.
|
||||
Added new files: G4PreCompoundAlpha.cc G4PreCompoundDeuteron.cc
|
||||
G4PreCompoundHe3.cc G4PreCompoundNeutron.cc G4PreCompoundProton.cc
|
||||
G4PreCompoundTriton.cc (Classes previously existed. Now they have more
|
||||
involved cross-section calculations).
|
||||
|
||||
19-September 2008 A.Howard hadr-pre-V09-01-09
|
||||
---------------------------------------------------
|
||||
Including Gunter's fix (see 11-August below) on top of ref-07
|
||||
(hadr-pre-V09-00-04), i.e. without JMQ's developments.
|
||||
|

11-August 2008 G.Folger
|
||||
-----------------------------------------------
|
||||
Rewrite algorithm in G4PreCompoundEmission::rho() to avoid frequent
|
||||
floating point overflow when using Precompund in combination
|
||||
with Binary Cascade.

Minor fixes and Coulomb barrier just for Wellisch's proton cross section
|
||||
(OPT=2)
|

|

23 July 2008 V.Ivanchenko hadr-pre-V09-01-07
|
||||
---------------------------------------------------
|
||||
Fixed mistake in tagging

23 July 2008 V.Ivanchenko hadr-pre-V09-01-06
|
||||
---------------------------------------------------
|
||||
Return back Coulomb barrier initialisation (J.M.Quesada)
|
||||
|
||||
27 June 2008 V.Ivanchenko hadr-pre-V09-01-05
|
||||
---------------------------------------------------
|
||||
Fixed G4PreCompoundNucleon and G4PreCompoundIon for
|
||||
Coulomb barrier, added protections for zero cross sections,
|
||||
OPT=2 is used (J.M.Quesada)
|
||||
|
||||
05 June 2008 J. M. Quesada hadr-pre-V09-01-04
|
||||
---------------------------------------------------
|
||||
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 ( OPT=2 in previous tag)
|
||||
|
||||
|
||||
15-May 2008 J. M.Quesada hadr-pre-V09-01-03
|
||||
-----------------------------------------------
|
||||
The retrieval of transition probabilities in G4PreCompoundModel.cc
|
||||
(for protection against unphysically crossing the landa_+=landa_- condition)
|
||||
was misplaced. Now it has been placed inside the preequilibrium transitions
|
||||
loop.
|
||||
|
||||
8-May 2008 J. M.Quesada hadr-pre-V09-01-02
|
||||
-----------------------------------------------
|
||||
Protection against non physical situation has been set: Equilibrium exciton number
|
||||
Neq (when reached, equilibrium regime starts) should correspond to equal transition
|
||||
probabilities "back" and "forth". Nevertheless, for heavy target (Neq is big even
|
||||
for low incident energies) after first emission this condition (equal trans. prob.)
|
||||
is reached far before reaching corresponding Neq of the residual. Unless this "jump"
|
||||
to equilibrium is forced in this case, preequilibrium will be
|
||||
spuriously prolonged (as a side effect, with huge CPU consumption).
|
||||
G4PreCompoundModel and G4PreCompoundTransitions classes have been modified.
|
||||
|
||||
|
||||
1-May 2008 J. M.Quesada hadr-pre-V09-01-01
|
||||
-----------------------------------------------
|
||||
- First trial with cvs. 00 skipped by mistake.
|
||||
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. In all particle header files:
|
||||
G4PreCompoundNucleon.hh ,G4PreCompoundNeutron.hh,G4PreCompoundProton.hh, G4PreCompoundIon.hh, G4PreCompoundDeuteron.hh, G4PreCompoundTriton.hh ,G4PreCompoundHe3.hh , G4PreCompoundAlpha.hh
|
||||
|
||||
|
||||
Soft cutoff transition from equilibrium to equilibrium has been suppressed (unphysical and not necessary anymore).In G4PreCompoundModel.
|
||||
|
||||
New transition probabilities :
|
||||
OPT=1 Gudima's formulae
|
||||
OPT=2 Machner parameterization of matrix elements for transitions (DEFAULT)
|
||||
|
||||
Level density is set to A/10 (Gudima's prescription).
|
||||
|
||||
Several bugs fixed (average xs in nucleon-nucleon xs in G4PreCompundTransitions.cc and emission probability formula in G4PreCompoundIon.cc ) .
|
||||

||||

|
||||
-----------------------------------------------
|
||||
