Computer programs for the Boltzmann collision matrix elements (Q1330590)

The package reported consists of routines to compute matrix elements in a Burnett function basis for a mixture of hard sphere gases, as also the loss integral of a Burnett mode and the functions themselves. The matrix elements involve the Clebsch-Gordan and Brody-Moshinsky coefficients, both of which are used here for unusually high values of their arguments. For the purpose of validation, both coefficients are computed using two different methods. Though written for hard sphere molecules, the package can, with only slight modification, be adapted to more general molecular models as well.
