Angular Distribution of Multiply Scattered Gamma Radiation from a Plane Isotropic Source

摘要

A method is given for calculating, within the framework of the moment‐method of Spencer and Fano, the angular distribution of radiation from a plane isotropic source. Essential use is made of the simplification introduced by a geometrical feature of radiation from such a source. Sample calculations are presented for a 1‐Mev source in water.
