New Method of Sampling the Klein-Nishina Probability Distribution for All Incident Photon Energies Above 1KeV (A Revised Complete Account).

摘要

A Monte Carlo method is given for determination of the scattered photon energy in the distribution required by the Klein-Nishina differential cross section for Compton collision,with a relative error not exceeding 2.2percent over the infinite range of incident energies above 1keV. A self-contained account is given of the method and the underlying theory,and is intended to supersede earlier less complete reports. A somewhat revised flow chart is included which should help to reduce running time. (ERA citation 03:041844)
