3. NATURE OF PHYSICAL PROBLEM SOLVED

Computes the following quantities of a polycrystalline material.
(1) unsymmetrized scattering cross sections.
(2) elastic cross section (total and transport).
(3) Legendre moments of scattering kernel.
(4) symmetrized scattering laws.
(5) inelastic cross sections (total and transport).
The programme is a revision of SUMMIT.
