| 50 | 17 July 2009 V. Uzhinsky (hadr-prtn-V09-02-01) |
|---|
| 51 | Improvement of FTF model: |
|---|
| 52 | A Status of nuclear nucleon involved in an interaction is introdused. |
|---|
| 53 | Status: 0 - spectator, 1 - involved nucleon, 2 - absorbed nucleon |
|---|
| 54 | (G4VSplitableHadron) |
|---|
| 55 | |
|---|
| 56 | A connection between a participant nucleon and a nuclear nucleon was |
|---|
| 57 | introsuced in G4InteractionContent. |
|---|
| 58 | |
|---|
| 59 | All of these allow to improve FTF model for pion obsorption on nuclei. |
|---|
| 60 | These required a lot of changes in FTF. |

| 65 | 9 July 2009 V. Uzhinsky (hadr-prtn-V09-01-03) |
|---|
| 66 | Charge-exchange was implemented for pn->np in elastic and inelastic |
|---|
| 67 | interactions simulated by FTF. Pion absorption by a nucleon was |
|---|
| 68 | implemented also. tag - hadr-string-diff-V09-02-02 |
|---|
| 69 | |
|---|
| 70 | Bug was fixed in G4VLongitudinalStringDecay.cc at calculation of |
|---|
| 71 | formation/creation time, c_light was inserted. Due to this string |
|---|
| 72 | tension parameter was set to the usual value (1 GeV/fm) in |
|---|
| 73 | G4LundStringFragmentation.cc. tag - had-hadronization-V09-02-02 |
|---|
| 74 | |
|---|
| 75 | New field was added in G4VSplitableHadron class (G4 bool Activation) |
|---|

|---|
| 77 | absorption of meson in nuclear collision generated by FTF. |
|---|

|---|
| 82 | G4QGSMFragmentation.cc and G4LundStringFragmentation.cc were |
|---|
| 83 | decoupled at calculation of formation time due to adding methods |
|---|
| 84 | and member in G4VLongitudinalStringDecay class for manipulation |
|---|
| 85 | with string tension. |
|---|
| 86 | |
|---|
| 87 | Memory leak was erased in G4QGSMFragmentation.cc and |
|---|
| 88 | G4VLongitudinalStringDecay.cc thank to Gunter. |

|---|
| 90 | 18 June 2008 V. Uzhinsky (hadr-prtn-V09-01-01) |

|---|
| 92 | operation of FTF. |

|---|
| 144 | |
|---|
| 145 | - Elastic hadron intra-nuclear nucleon scattering was inserted in |
|---|

| 147 | production together. |
|---|
| 148 | - Small re-orangement of FTF model was done. G4FTFCrossSection modules |
|---|
