---------------------------------------------------------------
* Please list in reverse chronological order (last date on top)
---------------------------------------------------------------
17 Nov 2011 Gunter Folger (hadr-util-V09-04-05)
-------------------------------------------------------------
- removed G4lrint(), G4lint(), and G4rint(); these are now in global
15 Sep 2011 Gabriele Cosmo (hadr-util-V09-04-04)
-------------------------------------------------------------
- Changed DLL export flag for symbols to G4HADRONIC_ALLOC_EXPORT.
14 Sep 2011 Gunter Folger (hadr-util-V09-04-03)
-------------------------------------------------------------
- G4Nucleus.hh: put obsolete interface GetN/GetZ into ifndef block.
this allows to try to compile without the obsolete interface.
09 Sep 2011 Michael Kelsey (hadr-util-V09-04-02)
-------------------------------------------------------------
- G4HadFinalState: Remove AddSecondary(G4HadSecondary*) interface. Improve
constness and add interfaces to merge two final states together.
- G4HadSecondary: Improve constness.
NOTE: These changes require modifications to a few packages:

reduce creation of temporary objects. Drop unneeded staleness flag.
6 Dec 2010 Dennis Wright (hadr-util-V09-03-02)
-------------------------------------------------------------
- G4Nucleus::ChooseParameters : fix fall-through case in which element = 0:
make last element in list the default

initialize theA, theZ. aEff, zEff to 0 in ctor
08 Mar 2010 G.Folger (hadr-util-V09-03-00)
-------------------------------------------------------------
- add interface for integer A&Z to G4Nucleus, and modify G4HadronicWhiteBoard
G4LightMedia, and G4ReactionDynamics to use the new interface.
06 Mar 2009 D.H. Wright for Tatsumi Koi (hadr-util-V09-02-00)
-------------------------------------------------------------
- G4StableIsotopes.cc - fill in missing isotope names
23 Jul 2008 D.H. Wright for Vladimir Uzhinskiy (hadr-util-V09-01-01)
--------------------------------------------------------------------
- G4ReactionDynamics::GenerateXandPt: fixed bug in momentum bin which
caused oscillatory behavior in spectrum: changed
x = std::min( 1.0, pt*(binl[l-1] + G4UniformRand()*(binl[l]-binl[l-1])/2 ) )
to
x = std::min( 1.0, pt*(binl[l-1] + G4UniformRand()*(binl[l]-binl[l-1]) ) )
9 Jul 2008 D.H. Wright (hadr-util-V09-01-00)
---------------------------------------------
- G4ReactionDynamics::GenerateXandPt: replace exit with G4Exception.
11 Oct 2007 F.W. Jones (hadr-util-V09-00-00)
--------------------------------------------
- G4LightMedia: fixed coding errors in inequalities for
charge exchange occurrence in PionPlusExchange,
KaonZeroShortExchange, and NeutronExchange.
13 August 2007 Dennis Wright (hadr-util-V08-03-00a)
---------------------------------------------------
- special CMS tag: geant4-08-03-ref-00 + hadr-util-V08-03-02.
On top of geant4-08-03-ref-00, this contains only array bounds, units
and backward peak fixes in G4ReactionDynamics
27 June 2007 Alex Howard (hadr-util-V08-03-03)
------------------------------------------------
- Removed DumpCoreOnHadronicException protection around Report() in
G4HadronicException, temporary fix to give output for G4NEUTRONHPDATA not set
12 June 2007 Dennis Wright (hadr-util-V08-03-02)
------------------------------------------------
- G4ReactionDynamics::TwoCluster : fix array bound violation when backward
nucleon count is 0
12 June 2007 Dennis Wright (hadr-util-V08-03-01)
------------------------------------------------
- G4ReactionDynamics::TwoCluster : fix two bugs:
1) sharp peak at 180 degrees for low and medium energies due to a units
error:
G4double totalE = kineticE + vMass;
was changed to
G4double totalE = kineticE*GeV + vMass;
Result is that particles from intra-nuclear cascade now have energies
~ 100 MeV instead of almost 0.
2) sharp peak at 180 degrees for low and medium energies and target nuclei
with Z > 6 due to incorrect sampling of polar angle:
replaced
G4double costheta =
1.0 + 2.0*std::log(1.0 - G4UniformRand()) / dtb;
with
G4double costheta =
1.0 + 2.0*std::log(1.0 - G4UniformRand()*factor) / dtb;
where factor = 1.0 - std::exp(-dtb) and dtb is momentum-dependent
10 June 2007 Dennis Wright (hadr-util-V08-03-00)
------------------------------------------------
- remove un-used classes G4Fuzzy, G4EffectiveCharge, G4ParticleVector
16 April 2007 Dennis Wright (hadr-util-V08-02-01)
-------------------------------------------------
- G4HadronicWhiteboard.hh, .cc : add methods to set process and model names
- G4ReactionDynamics.cc : add pi0 to anti-particle test
19 February 2007 V.Ivanchenko (hadr-util-V08-02-00)
----------------------------------------------------
- G4HadFinalState - add initialisation of energy deposition
11 December 2006 Dennis Wright (hadr-util-V08-01-01)
----------------------------------------------------
- G4ReactionDynamics::AddBlackTrackParticles
protect variables local_npnb, local_ndta from divide by zero
24 November 2006 Dennis Wright (hadr-util-V08-01-00)
----------------------------------------------------
- G4HadronicWhiteBoard:
replace GHAD message with
"Geant4 Hadronic Reaction Information" and use
G4Exception to kill run.
15 May 2006 Dennis Wright (hadr-util-V08-00-05)
-----------------------------------------------
- G4Nucleus:
replace code in method AtomicMass() with
return G4NucleiProperties::GetNuclearMass(A, Z);
in order to agree with other methods for getting nucleus mass.
Note: new version has electron masses subtracted, while old version
included them
02 May 2006 Dennis Wright (hadr-util-V08-00-04)
-----------------------------------------------
- G4ReactionDynamics:
1) in energy balance part of method GenerateXandPt, try removing pions and kaons
before removing nucleons
2) in method GetFinalStateNucleons improve and simplify nucleon counting
3) method SuppressChargedPions: check available CM energy before changing pion to
nucleon, also extend test for anti-particles to include strange particles
4) in methods GenerateXandPt and TwoCluster, call GenerateNBodyEvent a second time
if energy sum is violated, this time with total system energy
5) in method TwoCluster, use annihilation black track energy when annihilation channel
occurs
07 Apr 2006 Dennis Wright (hadr-util-V08-00-03)
-----------------------------------------------
- G4ReactionDynamics:
1) implement exact proton and neutron accounting to improve baryon number
conservation
2) add new method GetFinalStateNucleons which returns number of
protons and neutrons generated by the initial projectile-nucleon collision
3) replace spall argument in AddBlackTrackParticles with PinNucleus and
NinNucleus
- G4Nucleus:
1) add new method AnnihilationEvaporationEffects which calculates energy to
be given to evaporated nucleons after annihilation
2) add new methods GetAnnihilationPNBlackTrackEnergy and
GetAnnihilationDTABlackTrackEnergy to retrieve the values calculated above
13 Mar 2006 Dennis Wright (hadr-util-V08-00-02)
-----------------------------------------------
- G4Nucleus::GetFermiMomentum(),
G4ReactionKinematics::TwoBodyScattering() :
fix bug #838: momentum is now isotropic. Previously theta was
incorrectly sampled by pi*G4UniformRand().
15 Dec 2005 Dennis Wright (hadr-util-V08-00-01)
-----------------------------------------------
- G4ReactionDynamics.cc: add array bounds protection in TwoCluster
(cpar, gpar)
30 Nov 2005 Gabriele Cosmo (hadr-util-V07-01-01)
-----------------------------------------------
- Trivial fix in G4ReactionKinematics and G4Nucleus for support of
CLHEP-2.0.X series.
