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.
