35 // --------- G4LowEnergyPolarizedCompton class -----
36 //
37 // by G.Depaola & F.Longo (21 may 2001)
38 // 24 May 2001 - MGP Modified to inherit from G4VDiscreteProcess
39 // 25 May 2001 - MGP Added protections to avoid crashes
40 //
41 // 17 October 2001 - F.Longo Major revision according to design iteration
42 //
43 // 21 February 2002 - F.Longo Revisions with A.Zoglauer and G.Depaola
44 // - better description of parallelism
45 // - system of ref change method improved
46 //
47 //
48 // Class description:
49 // Low Energy electromagnetic process, Polarised Compton scattering
