Studies in nuclear photodisintegration

Abstract

The experimental results pertaining to nuclear photdisintegration and the giant resonance are summarised, It is pointed out that although most of the observed nucleon emission is characteristic of a decaying compound nucleus, there generally remains a component which is presumed to arise from direct interactions, The principal theoretical models proposed to account for the absorption are briefly discussed; the relationship between the collective and independent particle model descriptions is indicated, and it is shown that the latter formulation is able to account for the propertied of the direct component as far as they are known. The points at which some of the experiments described in later chapters provide additional information about direct emission and test the predictions of the single particle theory are indicated.
