Abstract

By using a large-acceptance position-sensitive silicon detector array in coincidence with the high-resolution Munich Q3D spectrograph, unambiguous measurements have been made of the absolute α-particle decay widths from excited states in O16* in the energy range 13.85 to 15.87 MeV. Carbon targets have been bombarded with 42-MeV Li6 beams to induce 612C(36Li, d)816O* reactions. The deuteron ejectiles were measured in the Q3D and the results gated by He4+C12 breakup products detected in the silicon array, the efficiency of which was modeled using Monte Carlo simulations.
