32 //
33 // Author: Andreas Schaelicke and Pavel Starovoitov
34 //
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 (ME squared, without phase space)
42 // incomming positron (along positive z direction) scatters at an electron at rest
43 // * phi denotes the angle between the scattering plane and the incoming PRF X-axis
44 // * all stokes vectors refer to spins in the Global System (X,Y,Z)
