Photoproduction of Single Charged Pions from Deuterium and Hydrogen

Abstract
Differential cross sections for the photoproduction of single charged pions from deuterium and hydrogen have been measured at pion center-of-mass angles between 30° and 90° and at photon energies between 3.0 and 3.7 GeV. The ratio of π to π+ cross sections from deuterium is found to be appreciably smaller than 1.
