# ABSFAC: A program for the calculation of the absorption during scattering in multifaceted crystals and similar samples

## Description

Abstract ABSFAC is a FORTRAN program that rapidly and efficiently calculates the absorption factor, T, in multifaceted convex crystals and in other materials whose shape can be modeled by a convex polyhedron. The program also calculates derivatives of T with respect to small outward movements of the polyhedron faces and the mean path length for the scattered rays. Although written for X-ray scattering, the programme is relevant to other scattering provided the underlying assumptions are valid. The pro...
