//------------------ G4PhotoElectricEffect physics process ------------------
|
|
// by Michel Maire, 24 May 1996
|
|
//
|
|
// 12-06-96, Added SelectRandomAtom() method and new data member
|
|
// for cumulative total cross section, by M.Maire
|
|
// 21-06-96, SetCuts implementation, M.Maire
|
|
// 17-09-96, Dynamic array PartialSumSigma
|
|
// split ComputeBindingEnergy(), M.Maire
|
|
// 08-01-97, crossection table + meanfreepath table, M.Maire
|
|
// 13-03-97, adapted for the new physics scheme, M.Maire
|
|
// 13-08-98, new methods SetBining() PrintInfo()
|
|
// 17-11-98, use table of atomic shells in PostStepDoIt, mma
|
|
// 06-01-99, Sandia crossSection below 50 keV, V.Grichine mma
|
|
// 03-08-01, new methods Store/Retrieve PhysicsTable (mma)
|
|
// 06-08-01, BuildThePhysicsTable() called from constructor (mma)
|
|
// 19-09-01, come back to previous process name "phot"
|
|
// 20-09-01, DoIt: fminimalEnergy = 1*eV (mma)
|
|
// 01-10-01, come back to BuildPhysicsTable(const G4ParticleDefinition&)
|
|
// 10-01-02, moved few function from icc to cc
|
|
// 17-04-02, Keep only Sandia crossSections. Remove BuildPhysicsTables.
|
|
// Simplify public interface (mma)
|
|
// 29-04-02, Generate theta angle of the photoelectron from Sauter-Gavrila
|
|
// distribution (mma)
|
|
// 13-08-04, suppress icc file; make public ComputeCrossSectionPerAtom() (mma)
|
|
// 21-04-05, Redesign - use G4VEmProcess interface (V.Ivanchenko)
|
|
// 02-05-05, move ParticleChange actions in model (mma)
|
|
// 04-05-05, Make class to be default (V.Ivanchenko)
