Level structure of $^{\mathrm{96}}$Mo from the (d,p$\gamma )$ measurement with $^{\mathrm{95}}$Mo beams and GODDESS
ORAL
Abstract
When used in conjunction with radioactive ion beams in inverse kinematics, the surrogate reactions method (SRM) can inform neutron capture cross sections on isotopes of interest to the r process. The use of SRM requires a modern nuclear reaction model of the (d,p) reaction that includes deuteron break-up and a level scheme that is as detailed as possible. Recently, the (d, p) reaction was confirmed as a surrogate for (n, $\gamma )$ reactions in normal kinematics using a $^{\mathrm{95}}$Mo target.$^{\mathrm{1}}$ To extend the benchmarking of the surrogate reactions method to inverse kinematics, a (d, p$\gamma )$ measurement with $^{\mathrm{95}}$Mo beams was performed using GODDESS (Gammasphere ORRUBA: Dual Detectors for Experimental Structure Studies) at ATLAS. This GODDESS experiment is the first (d, p$\gamma )$ measurement on $^{\mathrm{95}}$Mo to populate two-neutron configurations of states below 4 MeV. This (d, p$\gamma )$ study is an important step in refining the reaction theory and current level scheme of $^{\mathrm{96}}$Mo for use in the surrogate reaction analysis. Preliminary results detailing the differential cross sections of low-lying states in $^{\mathrm{96}}$Mo and extension of the $^{\mathrm{96}}$Mo level scheme will be presented. [1] A.
