SUPERTOG-JR, a code generating transport group constants, energy deposition coefficients and atomic displacement constants with ENDF/B

SUPERTOG-JR generates (a) the neutron cross sections for neutron transport calculation and (b) the energy deposition coefficients and the atomic displacement cross sections. The function (a) is the same as in SUPERTOG-3 except the addition of an optional routing generating the inelastic scattering matrix in the level density model. The function (b) developed newly treats both in nearly the same mathematical formulae except for the conversion scheme of kinetic energy of neutrons onto the material atoms. The displacement cross section is calculated with the Lindhard model. (auth.)
