Developing the (d,p$\gamma$) reaction as a surrogate for (n,$\gamma$) in inverse kinematics

ORAL

Abstract

The r-process that proceeds via (n,$\gamma$) reactions on neutron-rich nuclei is responsible for the synthesis of about half of the elements heavier than iron. Because (n,$\gamma$) measurements on short-lived isotopes are not possible, the (d,p$\gamma$) reaction is being investigated as a surrogate for (n,$\gamma$). Of particular importance is validating a surrogate in inverse kinematics. Therefore, the $^{95}$Mo(d,p$\gamma$) reaction was measured in inverse kinematics with stable beams from ATLAS and CD$_{2}$ targets. Reaction protons were measured in coincidence with gamma rays with GODDESS $-$ Gammasphere ORRUBA: Dual Detectors for Experimental Structure Studies. The Oak Ridge Rutgers University Barrel Array (ORRUBA) of position-sensitive silicon strip detectors was augmented with annular arrays of segmented strip detectors at backward and forward angles, resulting in a high-angular coverage for light ejectiles. Preliminary results from the $^{95}$Mo(d,p$\gamma$) study will be presented.
