X-ray scattering datafiles (This process MUST be automated in the future! ;) )
Obtained from NIST: http://physics.nist.gov/cgi-bin/ffast/ffast.pl
1) Use the tool get_xray_db_data - requires bash and wget, e.g.:
./get_xray_db_data Mo Mo.txt
2) Edit Mo.txt using an editor and strip out any html tags
3) "Massage" the header to make it similar to
#Be (Z 4)
#Atomic weight: A[r] 9.012180
#Nominal density: rho 1.8450
#sigma[a](barns/atom) = [mu/rho](cm^2 g^-1) × 1.49651E+01
#E(eV) [mu/rho](cm^2 g^-1) = f[2](e atom^-1) × 4.66927E+06
