-------------------------------------------------------------------------------
## 2025-11-04 Vladimir Ivanchenko (hadr-pre-V11-03-08)
- G4PreCompoundModel - send to evaporation all fragments with excitation energy
exceed energy limit
## 2025-08-07 Vladimir Ivanchenko (hadr-pre-V11-03-07)
- G4PreCompoundModel - increased limit of the pre-compound loop from
100 to 300 to suppress rare warnings seen in geant-val tests.
## 2025-07-08 Vladimir Ivanchenko (hadr-pre-V11-03-06)
- G4VPreCompoundFragment - optimized initial step of integrator from 1 MeV
to 0.5 MeV, increazed tolerance from 1.05 to 1.1.
## 2025-07-04 Vladimir Ivanchenko (hadr-pre-V11-03-05)
- G4PreCompoundModel - multi-fragmentation model is moved from the
G4ExcitationHandler to be called before this pre-compound model for very
hot fragments. The default excitation energy limit is very high, as it was
in the case of G4ExcitationHandler. So, this modification is pure technical
and should not affect any result. Comments to the class are improved.
## 2025-06-04 Vladimir Ivanchenko (hadr-pre-V11-03-04)
- G4PreCompoundFragment, G4PreCompoundNucleon, G4PreCompoundIon - updated
computation of inverse x-section, added factor to x-section proposed by
Dostorovsy.

utility G4DeexPrecoUtility.
## 2025-03-05 Vladimir Ivanchenko (hadr-pre-V11-03-02)
- G4VPreCompoundFragment, G4PreCompoundFragment, G4HETCFragment, - use the
new utility class G4VSIntegration, which allows to simplify code,
results are practically not affected.
## 2025-02-15 Vladimir Ivanchenko (hadr-pre-V11-03-01)
- G4PreCompoundFragment - updated algorithms of integration of probabilities
and sampling of final state (expected more accurate spectra of particles).
## 2025-01-26 Vladimir Ivanchenko (hadr-pre-V11-03-00)
- G4PreCompoundModel, G4PreCompoundTransition, G4PreCompoundEmission - introduced
verbose flag and extended printout needed to debug, removed old commented
prinout lines; added an option to use alternative precompound models,
which may be done via configuration without change of interface to consumer code.
- G4PreCompoundInterface, G4PreCompoundTransitionInt, G4PreCompoundEmissionInt -
new classes with alternative precompound model.
## 2024-09-09 Vladimir Ivanchenko (hadr-pre-V11-02-03)

instead of obsolete G4XSectionXS

memory leak at exit, moved initialisation to constructors, define OPTxs

fix format, removed unused data and methods
## 2022-11-26 Gabriele Cosmo (hadr-pre-V11-00-02)
- Fixed compilation warnings for implicit type conversions on macOS/XCode 14.1.
## 2022-11-21 V. Ivanchenko (hadr-pre-V11-00-01)
- G4PreCompoundModel - for case of a hyper-nucleus do not preform
pre-compound emission but only equivilibrium emission
## 2021-12-10 Ben Morgan (hadr-pre-V11-00-00)

Unphysical values at very low emission energies have been corrected (set
to 0); OPT=1 ( OPT=2 in previous tag)

-----------------------------------------------
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 ) .

-----------------------------------------------
- Removed compilation warning on unused parameter in G4PreCompoundIon.cc
11-October 2007 A.Howard hadr-pre-V09-00-03
-----------------------------------------------
- Corrected for integer arithmetic bug in G4PreCompoundModel.cc
(ratio of charged to neutral excitons)
01-October 2007 A.Howard hadr-pre-V09-00-02
-----------------------------------------------
- Protected Rj (Q_beta) factor against divide by zeroes (should never happen?)
The following files have been modified:
G4PreCompoundAlpha.hh, G4PreCompoundDeuteron.hh, G4PreCompoundHe3.hh,
G4PreCompoundTriton.hh, G4PreCompoundNeutron.hh, G4PreCompoundProton.hh

- Development tag incorporating further suggestions/corrections from
Jose-Manuel Quesada particularly with respect to light ion production.
The following files have been modified:
G4PreCompoundIon.cc, G4PreCompoundDeuteron.hh, G4PreCompoundHe3.hh,
G4PreCompoundTriton.hh, G4PreCompoundAlpha.hh, G4PreCompoundIon.hh,
G4VPreCompoundIon.hh (unused?)
23-July 2007 A.Howard hadr-pre-V09-00-00
----------------------------------------------
- Development tag incorporating the suggestions/corrections of Jose-Manuel
Quesada. These should reflect the literature and units expected for the
exciton model. The following files have been modified:
G4PreCompoundNucleon.hh, G4VPreCompoundNucleon.hh, G4PreCompoundAlpha.hh,
G4PreCompoundHe3.hh, G4PreCompoundDeuteron.hh, G4PreCompoundNeutron.hh,
G4PreCompoundProton.hh, G4PreCompoundTriton.hh
G4VPreCompoundIon.cc, G4PreCompoundIon.cc, G4PreCompoundModel.cc,
G4VPreCompoundFragment.cc, G4PreCompoundTransitions.cc,
G4PreCompoundNucleon.cc, G4VPreCompoundNucleon.cc
The main changes are:
- introducing an Rj factor into the probability calculation,
- correcting the units for the Pauli Blocking Factor - missing a g factor,
- decreasing the number of charged particles if the number excitons is
decreased (previously this number was only increased with increasing
excitons).
