Abstract
Proton and deuteron groups scattered from and targets were measured with a magnetic spectrograph. Accurate values for the level positions up to approximately 5-Mev excitation were obtained. One level in each nucleus failed to scatter deuterons. The operation of an isobaric spin-selection rule seems to be the most reasonable explanation of this behavior.
