Name:_atom_type_scat.hi_ang_Fox_c0
Definition:
The set of data items used to define Fox et al. coefficients
for generation of high-angle (2.0 < s < 6.0 Å^-1^) X-ray scattering factors.
f(s) = exp[Sum(c~i~ * s^i^, i=0:3)]
where s = sin(θ)/λ, θ is the diffraction angle and λ is the wavelength
of the incident radiation in angstroms.
