Detailed Description

Constants describing material effects for a surface (for an angle of incidence = pi/2). If thickness = d: radLen = d/X0 (used for description of multiple scattering and energy loss by electrons) xi = d[g/cm2] * 0.307075[MeV/(g/cm2)] * Z/A * 1/2 (used for energy loss acc. to Bethe-Bloch)
