Prospects for Surrogate Neutron Capture Measurements with Radioactive Ion Beams and GODDESS

Neutron capture reactions are responsible for the synthesis of almost all of the elements heavier than iron through s-process and r-process nucleosynthesis. Uncertainties in (n,γ) rates on neutron-rich nuclei can have significant impact on the predictions of observed r-process abundances for different astrophysical scenarios. The (d,pγ) reaction has recently been demonstrated to be a valid surrogate for (n,γ). This reaction has been measured in inverse kinematics with Gammasphere ORRUBA: Dual Detectors for Experimental Structure Studies (GODDESS) where the Gammasphere array of Compton-suppressed HPGe detectors is coupled to the Oak Ridge Rutgers University Barrel Array (ORRUBA) of position-sensitive silicon-strip detectors. Preliminary results from the (d,pγ) measurement with 134Xe beams are reported.
