CONTINUUM   ANGULAR   DISTRIBUTIONS


This directory contains data and tools for determining continuum angular distributions for use in nuclear reaction calculations within preequilibrium models and in evaluated data files.  We recommend the Kalbach systematics for most applications due to its wide-range applicability, and due to the fact that emission spectra can then be represented in a convenient compact form in the evaluated data libraries. A computer code kalbach_systematics.for is included in the RIPL library to compute the Kalbach systematics angular distributions.   We also recommend the use of a physics-based formula by Chadwick and Oblozinský for analyses in which a fundamental physical derivation is preferred. A code losalamos_analytical.for is provided to calculate angular distributions within this theory.

The directory is comprised of the subdirectories RECOMMENDED and OTHER_FILES:
