|---|
| 20 | First implementation of the Internal Conversion in the G4PhotonEvaporation class |
|---|
| 21 | |
|---|
| 22 | The following classes have been modified: |
|---|
| 23 | |
|---|
| 24 | G4NuclearLevelManager.hh |
|---|
| 25 | G4DiscreteGammaDeexcitation.hh G4PhotonEvaporation.hh |
|---|
| 26 | G4DiscreteGammaTransition.hh G4VGammaDeexcitation.hh |
|---|
| 27 | G4NuclearLevel.hh G4VGammaTransition.hh |
|---|
| 28 | |
|---|
| 29 | Atomic Relaxation can be included from the low energy EM group but Auger electron |
|---|
| 30 | production is switched. |
|---|
| 31 | |
|---|
| 32 | Instructions on how to activate the Internal Conversion Model (ICM) |
|---|
| 33 | Conversion electron emission is a competting process to gamma emission in |
|---|
| 34 | nuclear photo-evaporation. It has been implemented in the new G4PhotoEvaporation class and |
|---|
| 35 | it contolled by the following public methods which have been added to the class. |
|---|
| 36 | |
|---|
| 37 | void SetICM (G4bool); |
|---|
| 38 | |
|---|
| 39 | To activate or deactivate the ICM in photo evaporation process. ICM is off by default. |
|---|
| 40 | |
|---|
| 41 | void RDMForced (G4bool); |
|---|
| 42 | |
|---|
| 43 | Special method used primarily by G4RadioactiveDecay() to force photoevaporation of |
|---|
| 44 | long lived levels. |
|---|
| 45 | If this is set to true the evaporation will bypass the MaxHalfLife test as set by |
|---|
| 46 | the SetMaxHalfLife() method. |
|---|
| 47 | |
|---|
| 48 | void SetMaxHalfLife(G4double) ; |
|---|
| 49 | |
|---|
| 50 | New method to stop evaporating long lived levels. Default is 1e-6 seconds |
|---|
| 51 | |
|---|
| 52 | void SetEOccupancy( G4ElectronOccupancy) ; |
|---|
| 53 | |
|---|
| 54 | To set the orbital electron configuration of the nuclei |
|---|
| 55 | |
|---|
| 56 | G4ElectronOccupancy GetEOccupancy () { return _eOccupancy;} ; |
|---|
| 57 | |
|---|
| 58 | To retrieve the modified eletron configuration. |
|---|
| 59 | |
|---|
| 60 | G4int GetVacantShellNumber () { return _vShellNumber;}; |
|---|
| 61 | |
|---|
| 62 | To obtained the vacant shell number, for further atomic relaxation |
|---|
| 63 | |
|---|
| 64 | void SetARM (G4bool val) ; |
|---|
| 65 | |
|---|
| 66 | To activate or deactivate the atomic relaxation process. ARM is off by default. |
|---|
| 67 | |
