Using GODDESS instrumentation to explore (n,γ) surrogate reactions through 95Mo(d,pγ)*

The rapid neutron capture process is responsible for the synthesis of more than half of the elements heavier than iron. Unfortunately, the nuclei near the r-process path are too short-lived for the (n,γ) reaction to be studied in the laboratory setting. A possible surrogate for the (n,γ) reaction is the (d,pγ) reaction. The 95Mo(d,pγ) reaction in inverse kinematics was investigated with GODDESS (Gammasphere ORRUBA: Dual Detectors for Experimental Structure Studies) with ATLAS at Argonne National Laboratory to benchmark the (d,pγ) reaction in inverse kinematics as a surrogate for the (n,γ) reaction. GODDESS pairs ORRUBA (Oak Ridge Rutgers University Barrel Array), which consists of twenty-four position-sensitive silicon strip detectors supplemented with annular silicon strip detectors at forward and backward angles, and Gammasphere, an array of 110 Compton-suppressed HPGe detectors with nearly full angular coverage, to measure particle-gamma ray coincidences. This talk will focus on the design of GODDESS instrumentation and will present preliminary results from the 95Mo(d,pγ) measurement.
