Validation of (d,p$\gamma$) as a Surrogate for (n,$\gamma$)

ORAL

Abstract

Although the importance of neutron capture on very exotic nuclei to nucleosynthesis is well known, direct measurements of these reactions are impossible. The (d,p$\gamma$) reaction at low energies was identified as a promising surrogate for (n,$\gamma$), as both reactions transfer relatively little angular momentum to the system. We report on a program to validate (d,p$\gamma$) as an (n,$\gamma$) surrogate reaction, using $^{95}$Mo as a target. The completed components of the experimental campaign include measurements of (d,p$\gamma$) in normal kinematics and of the intensities of transitions from excited states populated in (n,$\gamma$) as a function of neutron energies. Preliminary results from completed measurements and plans for an inverse kinematics measurement of $^{95}$Mo(d,p$\gamma$) will be presented.\\[4pt] This work was supported in part by the NSF, the U.S. DOE (DE-FG52-08NA28552 (Rutgers, ORAU), DE-AC52-07NA27344 (LLNL), DE-FG02-05ER41379 and DE-FG52-06NA26206 (Richmond).
