18 | -------------------------------------------- |
---|
19 | - G4LightMedia: fixed coding errors in inequalities for |
---|
20 | charge exchange occurrence in PionPlusExchange, |
---|
21 | KaonZeroShortExchange, and NeutronExchange. |

23 | 13 August 2007 Dennis Wright (hadr-util-V08-03-00a) |

24 | --------------------------------------------------- |
---|
25 | - special CMS tag: geant4-08-03-ref-00 + hadr-util-V08-03-02. |
---|
26 | On top of geant4-08-03-ref-00, this contains only array bounds, units |
---|
27 | and backward peak fixes in G4ReactionDynamics |

29 | 27 June 2007 Alex Howard (hadr-util-V08-03-03) |
---|
30 | ------------------------------------------------ |
---|
31 | - Removed DumpCoreOnHadronicException protection around Report() in |
---|
32 | G4HadronicException, temporary fix to give output for G4NEUTRONHPDATA not set |
---|
33 | |
---|
34 | 12 June 2007 Dennis Wright (hadr-util-V08-03-02) |
---|
35 | ------------------------------------------------ |
---|
36 | - G4ReactionDynamics::TwoCluster : fix array bound violation when backward |
---|
37 | nucleon count is 0 |
---|
38 | |
---|
39 | 12 June 2007 Dennis Wright (hadr-util-V08-03-01) |
---|
40 | ------------------------------------------------ |
---|
41 | - G4ReactionDynamics::TwoCluster : fix two bugs: |
---|
42 | 1) sharp peak at 180 degrees for low and medium energies due to a units |
---|
43 | error: |
---|
44 | G4double totalE = kineticE + vMass; |
---|
45 | was changed to |
---|
46 | G4double totalE = kineticE*GeV + vMass; |
---|
47 | Result is that particles from intra-nuclear cascade now have energies |
---|
48 | ~ 100 MeV instead of almost 0. |
---|
49 | |
---|
50 | 2) sharp peak at 180 degrees for low and medium energies and target nuclei |
---|
51 | with Z > 6 due to incorrect sampling of polar angle: |
---|
52 | replaced |
---|
53 | G4double costheta = |
---|
54 | 1.0 + 2.0*std::log(1.0 - G4UniformRand()) / dtb; |
---|
55 | with |
---|
56 | G4double costheta = |
---|
57 | 1.0 + 2.0*std::log(1.0 - G4UniformRand()*factor) / dtb; |
---|
58 | where factor = 1.0 - std::exp(-dtb) and dtb is momentum-dependent |
---|
59 | |
---|
60 | 10 June 2007 Dennis Wright (hadr-util-V08-03-00) |

79 | ---------------------------------------------------- |
---|
80 | - G4HadronicWhiteBoard: |
---|
81 | replace GHAD message with |
---|
82 | "Geant4 Hadronic Reaction Information" and use |
---|
83 | G4Exception to kill run. |
---|
84 | |
---|
85 | 15 May 2006 Dennis Wright (hadr-util-V08-00-05) |
---|
86 | ----------------------------------------------- |
---|
87 | - G4Nucleus: |
---|
88 | replace code in method AtomicMass() with |
---|
89 | |
---|
90 | return G4NucleiProperties::GetNuclearMass(A, Z); |
---|
91 | |
---|
92 | in order to agree with other methods for getting nucleus mass. |
---|
93 | Note: new version has electron masses subtracted, while old version |
---|
94 | included them |
---|
95 | |
---|
96 | 02 May 2006 Dennis Wright (hadr-util-V08-00-04) |

---|
98 | - G4ReactionDynamics: |
---|
99 | 1) in energy balance part of method GenerateXandPt, try removing pions and kaons |
---|
100 | before removing nucleons |
---|
101 | 2) in method GetFinalStateNucleons improve and simplify nucleon counting |
---|
102 | 3) method SuppressChargedPions: check available CM energy before changing pion to |
---|
103 | nucleon, also extend test for anti-particles to include strange particles |
---|
104 | 4) in methods GenerateXandPt and TwoCluster, call GenerateNBodyEvent a second time |
---|
105 | if energy sum is violated, this time with total system energy |
---|
106 | 5) in method TwoCluster, use annihilation black track energy when annihilation channel |
---|
107 | occurs |
---|

---|
109 | 07 Apr 2006 Dennis Wright (hadr-util-V08-00-03) |
---|
110 | ----------------------------------------------- |
---|
111 | - G4ReactionDynamics: |
---|
112 | 1) implement exact proton and neutron accounting to improve baryon number |
---|
113 | conservation |
---|
114 | 2) add new method GetFinalStateNucleons which returns number of |
---|
115 | protons and neutrons generated by the initial projectile-nucleon collision |
---|
116 | 3) replace spall argument in AddBlackTrackParticles with PinNucleus and |
---|
117 | NinNucleus |
---|
118 | |
---|
119 | - G4Nucleus: |
---|
120 | 1) add new method AnnihilationEvaporationEffects which calculates energy to |
---|
121 | be given to evaporated nucleons after annihilation |
---|
122 | 2) add new methods GetAnnihilationPNBlackTrackEnergy and |
---|
123 | GetAnnihilationDTABlackTrackEnergy to retrieve the values calculated above |

---|
128 | G4ReactionKinematics::TwoBodyScattering() : |
