Abstract

The ⁷⁵As(d,pγ) reaction in inverse kinematics as a surrogate for neutron capture was performed at Oak Ridge National Laboratory using a deuterated plastic target. The intensity of the 165 keV γ-ray from ⁷⁶As in coincidence with ejected protons, from exciting ⁷⁶As above the neutron separation energy populating a compound state, was measured. A tight geometry of four segmented germanium clover γ-ray detectors together with eight ORRUBA-type silicon-strip charged-particle detectors was used to optimize geometric acceptance. The preliminary analysis of the ⁷⁵As experiment, and the eïňČcacy and future plans of the (d,pγ) surrogate campaign in inverse kinematics, are discussed.
