GRASER: A kinetics code for study of neutron-pumped gamma-ray laser systems
Abstract
Description, listing, sample plots, and operating instructions are given of a computer code for the CDC-6600 which calculates the time-dependence of populations of isomeric nuclear states and the time- and space-dependence of the vector potential of a plane wave of recoilless gamma radiation initiated by spontaneous emission and amplified by stimulated emission in a medium of specified properties. The code is based upon a continuous-function approximation of the neutron flux arising from a fast source burst of userspecified intensity in an infinite hydrogenous moderator. A variety of properties of the nuclear transition and of the medium may be specified by the user.
