New:
- Add energy dependence for rare earths (Lynn and Seeger, 1990).
Modified:
- Use complex b_c when computing the coherent cross section, leading to
correct values of sigma_c and sigma_i for materials with large absorption.
With this change the tabulated values for B[10] are now shown to be
self-consistent within a few percent.
Breaking changes:
- Neutron scattering factors are returned with one value for each wavelength
even for energy independent elements. Previous versions returned a scalar
if the returned value was identical for each wavelength.
