---|
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. |
---|
