Title: Pair spectrograph measurements of the radiations from deuteron bombardment of carbon-13, nitrogen-14, beryllium-9, lithium-7, and boron-11
Author: Sippel, Robert F.
Degree: Doctor of Philosophy thesis
Abstract: The measurement of gamma-rays emitted by nuclei under heavy particle bombardment is an important source of information concerning nuclear level structure. Unfortunately, in the region of light nuclei the gamma-ray energies are large and their accurate measurement is difficult. Most high energy gamma-ray measurements in the past have been made with detectors of such poor resolution as to obscure the details of complex spectra. For this reason considerable effort has been expended to improve the performance of a magnetic lens pair spectrometer for gamma-ray measurements. Sufficient progress has been made so that it was thought worth while to survey the gamma-rays from a number of nuclear reactions with the instrument in its present form. The results reported here together with those of R. D. Bent (Ph.D. Thesis) constitute such a survey. In addition to the measurement of gamma-rays the spectrometer provides a means of detecting nuclear pairs ejected in J = 0 to J = 0 transitions. A specific attempt was made to detect such pi states in the several nuclei where they have been proposed.
