0030 //                   by Michel Maire, 24 May 1996
0031 //
0032 // 11-06-96, Added GetRandomAtom() method and new data member
0033 //           for cumulative total cross section, by M.Maire
0034 // 21-06-96, SetCuts inplementation, M.Maire
0035 // 16-09-96, Dynamical array PartialSumSigma, M.Maire
0036 // 14-01-97, crossection table + meanfreepath table.
0037 //           PartialSumSigma removed, M.Maire
0038 // 14-03-97, new physics scheme for geant4alpha, M.Maire
0039 // 13-08-98, new methods SetBining() PrintInfo()
0040 // 03-08-01, new methods Store/Retrieve PhysicsTable (mma)
0041 // 06-08-01, BuildThePhysicsTable() called from constructor (mma)
0042 // 19-09-01, come back to previous ProcessName: "conv"
0043 // 20-09-01, DoIt: fminimalEnergy = 1*eV (mma)
0044 // 01-10-01, come back to BuildPhysicsTable(const G4ParticleDefinition&)
0045 // 13-08-04, suppress .icc file
0046 //           public ComputeCrossSectionPerAtom() and ComputeMeanFreePath() (mma)
0047 // 09-11-04, Remove Retrieve tables (V.Ivantchenko)
0048 // 19-04-05, Redesign - use G4VEmProcess interface (V.Ivantchenko)
0049 // 04-05-05, Make class to be default (V.Ivanchenko)
0050 // 09-08-06, add SetModel(G4VEmModel*) (mma)
0051 // 12-09-06, move SetModel(G4VEmModel*) in G4VEmProcess (mma)
