Detailed Description

Rayleigh angular parameters to fit tabulated form factors.

The form factors FF (constructed by the RayleighModel) are:

\[ FF(E,cos)^2 = \Sigma_{j} \frac{a_j}{[1 + b_j x]^{n}} \]

where \( x = E^{2}(1 - \cos\theta) \) and n is the high energy slope of the form factor and a and b are free parameters to obtain the best fit to the form factor. The unit for the energy (E) is in MeV.
