Scattering of Alpha Particles

Abstract

A resume of early and recent alpha -particle scattering experiments is given, including an account of the first cyclotron experiments. Various models used to explain the alpha -nucleus interaction are outlined, including the Aknezier-Pomeranchuk-Blair models, the Ford-Wheeler model, the classical strong absorption model, and various optical models. The validity of each of these models using heavy and light target nuclei is investigated. Theory and experimental data on elastic scattering and total reduction cross sections are presented. (T.F.H.)
