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. |

---|
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. |

81 | 23 June 2008 V. Uzhinsky (hadr-prtn-V09-01-02) |
---|
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. |

---|
98 | 3. FTF parameters for pion-nucleon interactions were determined very rouhgly |
---|
99 | 4. Quiasi-elastic hadron-nucleus scattering was implemented in FTF |
---|

---|
147 | production together. |
---|

---|
149 | were re-named into G4FTFParameters and moved to /diffraction |
