Abstract
The yields of gamma rays resulting from Coulomb excitation have been measured for , , , , , , , , , , , , , , , , , , , , and . Angular distributions of the gamma radiation from the nuclei , , , , , , , , , , , , , and have been measured with respect to the incident proton beam on thick targets. The linear polarization of gamma rays following Coulomb excitation has been studied. A polarimeter based on the Compton scattering mechanism has been constructed and its effectiveness determined by measurements of the known polarization of gamma rays from excitation of 2+ levels in even-even nuclei. Polarization-direction measurements of several transitions in odd-mass nuclei have resolved the ambiguity either in the value of or in the spin of the excited state deduced from the angular distributions. Reduced transition probabilities for and transitions are obtained. In some instances these quantities are compared to the predictions of the collective model of the nucleus.
