Development and testing of a NaI(Tl) spectrometer is reported in this dissertation along with improvements of the resolution (FWHM) and FWTM) and refinements of the gain stabilization system. Extensive testing of the spectrometer at various ..gamma..-ray energies and an initial test at a proton energy E/sub p/ = 151 MeV is also presented. Theories describing radiative proton capture reactions in the energy region 20 MeV less than or equal to E/sub p/ less than or equal to 100 MeV are all based on the shell-model. These theories simplify for the doubly magic nucleus /sup 16/O. The study of the /sup 15/N(p,..gamma..)/sup 16/O reaction was performed with a NaI(Tl) spectrometer developed earlier at Ohio State University consisting of a central 25.4 cm theta x 30.5 cm NaI(Tl) crystal. Presented are experimental cross-sections at 60/sup 0/ over the energy region of interest and an angular distribution of the cross-sections and analyzing power measurements at a proton energy E/sub p/ = 49.69 MeV for the ground and various excited states. The Direct-Semidirect theory and Gamma, which is a single particle mechanism with meson exchange terms using the Direct equation, use a shell-model calculation with a 1p-1h configuration and are compared to the experimental results.
