1723 Jul 2008 D.H. Wright for Vladimir Uzhinskiy (hadr-util-V09-01-01)
18--------------------------------------------------------------------
19- G4ReactionDynamics::GenerateXandPt: fixed bug in momentum bin which
20  caused oscillatory behavior in spectrum:  changed
21    x = std::min( 1.0, pt*(binl[l-1] + G4UniformRand()*(binl[l]-binl[l-1])/2 ) )
22  to
23    x = std::min( 1.0, pt*(binl[l-1] + G4UniformRand()*(binl[l]-binl[l-1]) ) )
24
25 9 Jul 2008 D.H. Wright (hadr-util-V09-01-00)
26---------------------------------------------
27- G4ReactionDynamics::GenerateXandPt: replace exit with G4Exception.
28
2911 Oct 2007 F.W. Jones (hadr-util-V09-00-00)
30--------------------------------------------
31- G4LightMedia: fixed coding errors in inequalities for
32                charge exchange occurrence in PionPlusExchange,
33                KaonZeroShortExchange, and NeutronExchange.

3513 August 2007 Dennis Wright (hadr-util-V08-03-00a)
36---------------------------------------------------
37- special CMS tag: geant4-08-03-ref-00 + hadr-util-V08-03-02.
38  On top of geant4-08-03-ref-00, this contains only array bounds, units
39  and backward peak fixes in G4ReactionDynamics
40
4127 June 2007 Alex Howard (hadr-util-V08-03-03)
42------------------------------------------------
43- Removed DumpCoreOnHadronicException protection around Report() in
44  G4HadronicException, temporary fix to give output for G4NEUTRONHPDATA not set
45
4612 June 2007 Dennis Wright (hadr-util-V08-03-02)
47------------------------------------------------
48- G4ReactionDynamics::TwoCluster : fix array bound violation when backward
49    nucleon count is 0
50
5112 June 2007 Dennis Wright (hadr-util-V08-03-01)
52------------------------------------------------
53- G4ReactionDynamics::TwoCluster : fix two bugs:
54  1) sharp peak at 180 degrees for low and medium energies due to a units
55     error:
56         G4double totalE = kineticE + vMass;
57     was changed to
58         G4double totalE = kineticE*GeV + vMass;
59     Result is that particles from intra-nuclear cascade now have energies
60     ~ 100 MeV instead of almost 0.
61
62  2) sharp peak at 180 degrees for low and medium energies and target nuclei
63     with Z > 6 due to incorrect sampling of polar angle:
64     replaced
65         G4double costheta =
66            1.0 + 2.0*std::log(1.0 - G4UniformRand()) / dtb;
67     with
68         G4double costheta =
69            1.0 + 2.0*std::log(1.0 - G4UniformRand()*factor) / dtb;
70            where factor = 1.0 - std::exp(-dtb) and dtb is momentum-dependent
71
7210 June 2007 Dennis Wright (hadr-util-V08-03-00)
73------------------------------------------------
74- remove un-used classes G4Fuzzy, G4EffectiveCharge, G4ParticleVector
75
7616 April 2007 Dennis Wright (hadr-util-V08-02-01)
77-------------------------------------------------
78- G4HadronicWhiteboard.hh, .cc : add methods to set process and model names
79- G4ReactionDynamics.cc : add pi0 to anti-particle test
80
8119 February 2007 V.Ivanchenko (hadr-util-V08-02-00)
82----------------------------------------------------
83- G4HadFinalState - add initialisation of energy deposition
84
8511 December 2006 Dennis Wright (hadr-util-V08-01-01)
86----------------------------------------------------
87- G4ReactionDynamics::AddBlackTrackParticles
88  protect variables local_npnb, local_ndta from divide by zero
89
9024 November 2006 Dennis Wright (hadr-util-V08-01-00)
91----------------------------------------------------
92- G4HadronicWhiteBoard:
93  replace GHAD message with
94  "Geant4 Hadronic Reaction Information" and use
95  G4Exception to kill run.
96
9715 May 2006 Dennis Wright (hadr-util-V08-00-05)
98-----------------------------------------------
99- G4Nucleus:
100  replace code in method AtomicMass() with
101 
102    return G4NucleiProperties::GetNuclearMass(A, Z);
103
104  in order to agree with other methods for getting nucleus mass.
105  Note: new version has electron masses subtracted, while old version
106        included them
107
10802 May 2006 Dennis Wright (hadr-util-V08-00-04)
109-----------------------------------------------
110- G4ReactionDynamics:
111  1) in energy balance part of method GenerateXandPt, try removing pions and kaons
112     before removing nucleons
113  2) in method GetFinalStateNucleons improve and simplify nucleon counting
114  3) method SuppressChargedPions: check available CM energy before changing pion to
115           nucleon, also extend test for anti-particles to include strange particles
116  4) in methods GenerateXandPt and TwoCluster, call GenerateNBodyEvent a second time
117           if energy sum is violated, this time with total system energy
118  5) in method TwoCluster, use annihilation black track energy when annihilation channel
119     occurs 
120
12107 Apr 2006 Dennis Wright (hadr-util-V08-00-03)
122-----------------------------------------------
123- G4ReactionDynamics:
124  1) implement exact proton and neutron accounting to improve baryon number
125     conservation
126  2) add new method GetFinalStateNucleons which returns number of
127     protons and neutrons generated by the initial projectile-nucleon collision
128  3) replace spall argument in AddBlackTrackParticles with PinNucleus and
129     NinNucleus
130
131- G4Nucleus:
132  1) add new method AnnihilationEvaporationEffects which calculates energy to
133     be given to evaporated nucleons after annihilation
134  2) add new methods GetAnnihilationPNBlackTrackEnergy and
135     GetAnnihilationDTABlackTrackEnergy to retrieve the values calculated above
136

138-----------------------------------------------
139- G4Nucleus::GetFermiMomentum(),
140  G4ReactionKinematics::TwoBodyScattering() :
141
142    fix bug #838: momentum is now isotropic.  Previously theta was
143    incorrectly sampled by pi*G4UniformRand().
144
14515 Dec 2005 Dennis Wright (hadr-util-V08-00-01)
146-----------------------------------------------
147- G4ReactionDynamics.cc: add array bounds protection in TwoCluster
148                         (cpar, gpar)
149
15030 Nov 2005 Gabriele Cosmo (hadr-util-V07-01-01)
151-----------------------------------------------
152- Trivial fix in G4ReactionKinematics and G4Nucleus for support of
153  CLHEP-2.0.X series.
