Detailed Description

Calculates the ratio of Mott cross section to the Rutherford cross section.

This ratio is an adjustment of the cross section from a purely classical treatment of a point nucleus in an electronic cloud (Rutherford scattering) to a quantum mechanical treatment. The implementation is an interpolated approximation developed in [LQZ95] and described in the Geant Physics Reference Manual PRM section 8.4

The parameter cos_theta is the cosine of the scattered angle in the z-aligned momentum frame.
