_atom_type_scat.inv_Mott_Bethe_bs

Definition:

   
    The set of Gaussian exponent coefficients for use in the inverse Mott-Bethe
    relationship for generating X-ray scattering factors:
    [ b_1, b_2, ... , b_N ].

    f(s; Z~0~) =
    Z~0~ - 8π^2^ * r~B~ * s^2^ * {c + Sum[ a~i~ * exp(-b~i~ * s^2^), i=1:N]}

    where s = sin(θ)/λ, r~B~ is the Bohr radius, and Z~0~ is the number of
    electrons for the atom or ion. θ is the diffraction angle and λ is the
    wavelength of the incident radiation in angstroms.
