|

| 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

|

| 30 | ------------------------------------------------
|
|---|
| 31 | - Removed DumpCoreOnHadronicException protection around Report() in
|
|---|
| 32 | G4HadronicException, temporary fix to give output for G4NEUTRONHPDATA not set
|
|---|
| 33 |
|

| 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

|
|---|
| 80 | - G4HadronicWhiteBoard:
|
|---|
| 81 | replace GHAD message with
|
|---|
| 82 | "Geant4 Hadronic Reaction Information" and use
|
|---|
| 83 | G4Exception to kill run.

|
|---|
| 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
|

|
|---|
| 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
|

|
|---|
| 115 | protons and neutrons generated by the initial projectile-nucleon collision
|
|---|
| 116 | 3) replace spall argument in AddBlackTrackParticles with PinNucleus and
|

|
|---|
| 118 |
|
|---|
| 119 | - G4Nucleus:
