35 // Creation date: 12.01.2006
36 //
37 // Modifications:
38 // 16-01-06 included cross section as calculated by P.Starovoitov
39 //
40 // Class Description:
41 // * calculates the differential cross section
42 // incomming electron (along positive z direction) scatters at an electron at rest
43 // * phi denotes the angle between the scattering plane (defined by the
44 // outgoing electron) and X-axis
45 // * all stokes vectors refer to spins in the Global System (X,Y,Z)
