|
|
corrections in the case of large negatively charged particle
|

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

|
o G4UPiNuclearCrossSection: fixed bug for high Z (>83) atoms.
|
|
o Cache computation of std::pow() in GetCaptureCrossSection() method of

o G4InteractionCase: minor change in initialisation in constructor to
|
|
allow for porting on C++0x Standard.
|
|
+ models/CHIPS:
|
|
o Correction of mass in G4Quasmon, and fix of memory corruption in mass
|
|
calculation;
|
|
o Tuning of parameters and fixed bug in CHIPS fragmentation.
|
|
+ models/de_excitation:
|
|
o G4ExcitationHandler: activated Fermi-BreakUp by setting limits to the
|
|
default values (Z=9 and A=17) for this model.
|
|
+ models/high_energy:
|
|
o Fixed segmentation fault in G4HEKaonZeroLongInelastic and
|
|
G4HEKaonZeroShortInelastic due to local instantiation and subsequent
|
|

|
|
of K0 and anti-K0 outside the nucleus is now prohibited.
|
|
+ models/management:
|

|
|
in G4NeutronHPElasticData, G4NeutronHPInelasticData and

|
|
|
o Track:
|
|
-----

|
|
for property to indicate type of UserTrackInformation; helps in reducing
|
|
unnecessary memory churn reported by CMS.
|
|
+ Modified G4VUserTrackInformation::Print() method from pure-virtual to
|
|
simple virtual.
|
|
|

|
|
G4Trajectory::MergeTrajectory().
|
|
+ G4RichTrajectory and G4RichTrajectoryPoint: eliminated spaces in

|
G4AttValue values; G4AttValue() values are "None" for attributes
|
|
derived from zero pointers.

|
o Added density initialisation in MicrobeamPhantomConfiguration and
|
|
changed material/density selection.

|
|
with ions/protons.
|
|
o Corrected analysis-manager to solve a problem with the HBOOK output
|
|
