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 (E2/M1)/sup 1/2/ or in the spin of the excited state deduced from the angular distributions. Reduced transition probabilities for E2 and M1 transitions are obtained. In some instances these quantities are compared to the predictions of the collected model of the nucleus. (auth)
