Forward-backward electron yield ratio for α-particle induced emission from different materials

Abstract

In this work, the ratio of forward and backward electron yields for emission induced by the isotropic flux of - particles from zinc was measured. On the basis of the measured values and experimental data obtained in earlier experiments for other materials, a systematization of the electron yield ratio for forward and backward emission was done, and a relationship of the ratio with stopping power of an ion in a substance was found. The dependence of work function for various materials on the ratio of the electron emission yields was analyzed.
