| 22 | - Bug fix in G4PolarizedAnnihilationCrossSection
|
|---|
| 23 | error in calculation of polarisation dependent total cross section
|
|---|
| 24 | (wrong interactionLength for positrons in applications where,
|
|---|
| 25 | particle and media are polarised)
|
|---|
| 26 | - more general Cross section frame work:
|
|---|
| 27 | G4PolarizedAnnihilationCrossSection
|
|---|
| 28 | G4PolarizedBhabhaCrossSection
|
|---|
| 29 | G4PolarizedBremsstrahlungCrossSection
|
|---|
| 30 | G4PolarizedComptonCrossSection
|
|---|
| 31 | G4PolarizedGammaConversionModel
|
|---|
| 32 | G4PolarizedMollerCrossSection
|
|---|
| 33 | G4PolarizedPairProductionCrossSection
|
|---|
| 34 | G4VPolarizedCrossSection
|
|---|
| 35 | G4ePolarizedBremsstrahlungModel
|
|---|
| 36 | (removed dependencies to models; now cross sections can be used
|
|---|
| 37 | independent of any model, e.g. in a cross section calculator class)
|
|---|
| 38 | - add polarized photo electric effect:
|
|---|
| 39 | G4PolarizationHelper
|
|---|
| 40 | (new method GetRandomFrame, used when interaction frame is not
|
|---|
| 41 | well defined by outgoing particles)
|
|---|
| 42 | G4PolarizedPEEffectCrossSection
|
|---|
| 43 | (based on McMaster, Rev.Mod.Phys. 33 (1961) 8)
|
|---|
| 44 | G4PolarizedPEEffectModel
|
|---|
| 45 | (derived from G4PEEffectModel, adds polarisation transfer)
|
|---|
| 46 | G4PolarizedPhotoElectricEffect
|
|---|
| 47 | (derived from G4VEmProcess)
|
|---|
| 48 |
|

| 49 | 02 October 07: V.Ivanchenko (empolar-V09-00-01)
|
|---|
| 50 | G4eplusPolarizedAnnihilation - enabled AtRest
|
|---|
| 51 |
|
|---|
| 52 | 10 July 07: V.Ivanchenko (empolar-V09-00-00)
|
|---|
| 53 | 10 July 07: A.Schaelicke
|
|---|
| 54 | - G4VPolarizedCrossSection removed obsolete methodes and variables to
|
|---|
| 55 | clear "shadow" Warning on SUN CC
|
|---|
| 56 | - G4PolarizedCompton, G4ePolarizedIonisation,
|
|---|
| 57 | G4eplusPolarizedAnnihilation renamed local variable "particle" to
|
|---|
| 58 | avoid "shadow" Warning on SUN CC
|
|---|
| 59 | - G4PolarizedAnnihilationModel
|
|---|
| 60 | copied Initialise() method from G4eeToTwoGammaModel provide a
|
|---|
| 61 | ParticleChangeForGamma object, this avoids "shadow" Warning on SUNCC
|
|---|
| 62 | and reduces overhead in SampleSecondaries()
|
|---|
| 63 |
|
|---|
| 64 | 11 June 07: V.Ivanchenko (empolar-V08-03-02)
|
|---|
| 65 | - (A.Schaelicke) G4PolarizedCompton, G4ePolarizedIonisation,
|
|---|
| 66 | G4eplusPolarizedAnnihilation added method
|
|---|
| 67 | PostStepGetPhysicalInteractionLength in order to provide
|
|---|
| 68 | simulation of polarized target; the fix is required because of design
|
|---|
| 69 | change in utils
|
|---|
| 70 |
|
|---|
| 71 | 25 May 07: V.Ivanchenko (empolar-V08-03-01)
|
|---|
| 72 | - G4PolarizedCompton - fix compilation warning and incorrect usage of
|
|---|
| 73 | G4PhysicsVector
|
|---|
| 74 |
|
|---|
| 75 | 23 May 07: V.Ivanchenko (empolar-V08-03-00)
|
|---|
| 76 | - In all processes inherit from G4VEnergyLossProcess or G4VEmProcess
|
|---|
| 77 | remove method SecondaryPostStep;
|
|---|
| 78 | - G4VEmModel - changed interface of SampleSecondary method, it become
|
|---|
| 79 | void, extra parameter std::vector<G4DynamicParticle*>*, all
|
|---|
| 80 | classes using or inhereting this interface are modified.
|
|---|
| 81 |

|
|---|
| 91 |
|
|---|

|
|---|
| 99 | return statement and call to cross section.
|
|---|
| 100 | - G4PolarizedAnnihilationCrossSection : Initialize() bug fixed in
|
|---|
| 101 | dicing and sign in cross section.
|
|---|
| 102 | - G4PolarizedComptonCrossSection and G4PolarizedComptonModel:
|
|---|
| 103 | use correct convention of photon polarization vectors.
|
|---|
| 104 | - G4PolarizedMollerBhabhaModel : bug fixed in eps dicing, added
|
|---|

|
|---|
| 106 | to other polarized processes)
|
|---|
| 107 | - G4PolarizedBhabhaCrossSection and G4PolarizedMollerCrossSection :
|
