Abstract
We report on a study of the angular distribution in the reaction . Using a sample of 1904 events, we find that the contribution of helicity zero in the formation process is (90% C.L.), and that the normalized quadrupole amplitude in the radiative decay is . The normalized radiative decay octupole amplitude is found to be consistent with zero.
