Abstract

The experiments in this thesis are investigations of the medium to high energy nuclear photoeffect in various p-shell nuclei; this territory has not been well explored, and the present experiments represent a considerable advance.The high energy nuclear photoeffect is interesting because it is primarily a high momentum process, and should therefore be sensitive to short range effect between nucleons in the nucleus, effect to which most other nuclear processes are not sensitive.The set of data gathered is sufficiently extensive to show that the simplest interpretation of the high energy nuclear photoeffect is very reasonable. Also it is found that the independent particle shell model is incapable of explaining experiment; short range residual interactions are necessary but a popular method of introducing such interactions, relatively successful for some other high momentum processes, is shown to be inappropriate, an it is found that, in between the giant dipole resonance an the pi meson exchange. Chapter 1 of this thesis presents the details of the experiments performed and gives a general discussion of the nuclear photoeffect, Chapter 2 describes the experimental system, and Chapter 5 discusses the results. Mathematical machinery may be found in the Appendices.
