29 //------------ G4ComptonScattering physics process -----------------------------
30 // by Michel Maire, April 1996
31 //
32 // 28-05-96, DoIt() small change in ElecDirection, by M.Maire
33 // 10-06-96, simplification in ComputeMicroscopicCrossSection(), by M.Maire
34 // 21-06-96, SetCuts implementation, M.Maire
35 // 13-09-96, small changes in DoIt for better efficiency. Thanks to P.Urban
36 // 06-01-97, crossection table + meanfreepath table, M.Maire
37 // 05-03-97, new Physics scheme, M.Maire
38 // 28-03-97, protection in BuildPhysicsTable, M.Maire
39 // 07-04-98, remove 'tracking cut' of the scattered gamma, MMa
40 // 04-06-98, in DoIt, secondary production condition:
41 // range>std::min(threshold,safety)
42 // 13-08-98, new methods SetBining() PrintInfo()
43 // 15-12-98, cross section=0 below 10 keV
44 // 28-05-01, V.Ivanchenko minor changes to provide ANSI -wall compilation
45 // 13-07-01, DoIt: suppression of production cut for the electron (mma)
46 // 03-08-01, new methods Store/Retrieve PhysicsTable (mma)
47 // 06-08-01, BuildThePhysicsTable() called from constructor (mma)
48 // 17-09-01, migration of Materials to pure STL (mma)
49 // 20-09-01, DoIt: fminimalEnergy = 1*eV (mma)
50 // 01-10-01, come back to BuildPhysicsTable(const G4ParticleDefinition&)
51 // 17-04-02, LowestEnergyLimit = 1*keV
52 // 26-05-04, cross section parametrization improved for low energy :
53 // Egamma <~ 15 keV (Laszlo)
54 // 08-11-04, Remove Store/Retrieve tables (V.Ivanchenko)
55 // 09-03-05 Migrate to model interface
56 // and inherit from G4VEmProcess (V.Ivanchenko)
57 // 04-05-05, Make class to be default (V.Ivanchenko)
58 // 09-09-06, modify SetModel(G4VEmModel*) (mma)
59 // 12-09-06, move SetModel(G4VEmModel*) in G4VEmProcess (mma)
