data = read_endf(filename) import ENDF files, either using PyNE or slower/partial Matlab reader. Useful tokens for neutron scattering MF1/MT451 as 'info': ZA Standard material charge AWR Standard material mass AWI Mass of the projectile in neutron units EMAX Upper limit of energy range for evaluation. TEMP Target temperature (Kelvin) for Doppler broadening. MF7/MT4 as 'thermal_inelastic': LAT Flag indicating which temperature has been used to compute a and b LAT=0, the actual temperature has been used. LAT=1, the constant T0 = 0.0253 eV has been used (293 K). LASYM Flag indicating whether an asymmetric S(a,b) is given LASYM=0, S is symmetric. LASYM=1, S is asymmetric B=[sigma_free, E_elastic, A=mass/mn, E_max, ~, atom_multiplicity] sigma_bound = sigma_free*(A+1)^2/A^2 MF7/MT2 as 'thermal_elastic': SB Bound cross section (barns) [incoherent elastic LTHR=2] Format is defined at https://www.oecd-nea.org/dbdata/data/manual-endf/endf102.pdf (c) E.Farhi, ILL.
