|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ models/de_excitation:
|
|
o G4LevelManager, G4NuclLevel, G4LevelReader: reduce memory for description
|
|
of a level: each two integer parameters are packed into one integer value;
|
|
use only one set of probabilities of transition independently on use-case
|
|
(HEP or radioactive decay). Fill internal conversion coefficients into the
|
|
data structure only if a flag SetStoreAllLevels() is set to true; in the
|
|
last case, more memory required per isotope (~8 times).
|
|
o G4LevelManager: fixed unpacking of spin.
|
|
o G4LevelReader: fixed Ra228 problem; read all levels from a data file.
|
|
Fixed U235[0.076] problem: if value of alpha (relative probability of the
|
|
internal conversion) is 10^10, then assume that internal conversion will
|
|
go via outer levels and gamma emission has zero probability; internal
|
|
conversion is forced independently on other flags.
|
|
o G4NucLevel: in TransitionType, use % operator to correctly strip off
|
|
leading digit.
|
|
o G4GammaTransition: sample e- with kinetic energy corresponding to
|
|
transition between nuclear levels, ignoring atomic effects, when internal
|
|
conversion data are not filled but sampling e- emission is selected.
|
|
In SampleDirection(), fix to avoid only zero polarization returned;
|
|
return back sampling when initial state has angular moment but its
|
|
polarisation is random; also fix in order to comply with instructions in
|
|
G4PolarizationTransition for the call order and to properly initialize
|
|
the nuclear polarization.
|
|
Use SetExcitationEnergy() method of G4Fragment for keeping excitation
|
|
energy exact as in the database and avoid rare cases of event
|
|
non-reproducibility; added SetVerbose() method.
|
|
Fixed multipolarity based on the updated data-set.
|
|
Added control on printout; fixed thread unsafe check.
|
|
o G4PhotonEvaporation, G4GammaTransition: improved sampling and kinematics
|
|
for internal conversion. Added internal conversion in G4PhotonEvaporation
|
|
even if the data are not stored.
|
|
o G4PolarizationTransition: fix for computation of polarisation and
|
|
multi-polarity. Fix in SetGammaTransitionData().
|
|
Added SetVerbose() method; added protection from extra verbosity.
|
|
o G4ExcitationHandler: moved Dump() printout within Initialise()
|
|
method; print info if evaporation channels are changed.
|
|
Added local data member to control verbosity level.
|
|
o G4ExcitationHandler, G4PhotonEvaporation: use floating level number.
|
|
o G4DeexPrecoParameters: changed default time limit from 0.01 s to
|
|
1 microsecond. By default use uniform angular distribution in CM
|
|
system of precompound decay. Extended Dump() printout; make new data
|
|
structure the default. By default, use uniform angular distribution
|
|
in CM sytem of precompound decay.
|
|
Changed minimum excitation energy now set to 10 eV (was 100 eV).
|
|
o G4VEvaporation: added extra const access method.
|
|
o G4Evaporation: added data member to control verbosity level.
|
|
o Fixed case of event non-reproducibility due precision lost in
|
|
Lorentz transformations.
|
|
o G4LevelReader: in the case of broken file structure or absence of
|
|
a data file a fatal exception is issued.
|
|
Addressing problem report #1942.
|
|
+ models/im_r_matrix:
|
|
o G4VScatteringCollision: fixed memory leak in MT-mode.
|
|
Addressing problem report #1905.
|
|
+ models/radioactive_decay:
|
|
o G4ITDecay: in constructor, make G4PhotonEvaporation a class member
|
|
and initialize only once to avoid memory churn.
|
|
Added check on Z, A, excitation energy in order to be sure that
|
|
correlated gamma may be sampled; reset 4-momentum at rest when previous
|
|
nucleaus is reused; use floating level index when a new ion is created.
|
|
o G4RadioactiveDecay: temporarily switched off correlated gamma emission,
|
|
to limit observed event non-reproducibility violations.
|
|
+ models/util:
|
|
o G4Fragment: minor cleanup of check on excitation energy of a ground
|
|
state. Added method SetExcEnergyAndMomentum() allowing to preserve
|
|
excitation energy value without precision lost; 4-momentum is
|
|
recomputed. Added missing class member and accesors/modifiers for
|
|
floating levels number.
|
|
o Added control on printout in G4PolynomialPDF.
|
|
|
|
o Run:
|
|
---
|
|
+ Modifications to fix bug with reverse track splitting.
|
|
Added function ResetDidOneAdjPartReachExtSourceDuringEvent() to
|
|
G4AdjointSimManager and use it in G4AdjointPrimaryGeneratorAction.

|
|
|
|

|
|

switching. Added workaround to prevent empty second page in PS and PDF

|
+ RayTracer:
|
|
o G4RTXScanner: changed XA_RGB_BEST_MAP to XA_RGB_DEFAULT_MAP.

|
|
+ Patched data set for nuclides properties G4PhotonEvaporation-4.3.2:
|

|
|
multipolarity E0 as -1. Now considering E0,E1,M1, as 1,2,3,.....
|
|
The value of = is for unkown.
|
|
o Corrected correlated_gamma files z64.a148,z64.a149,z64.a150,z81.a194
