Neutron hole states in $^{131}$Sn studied via the $^{132}$Sn(d,t)$^{131}$Sn reaction
ORAL
Abstract
Knowledge of single-particle energies in the vicinity of exotic doubly-magic nuclei is of critical importance to understand evolution of nuclear structure. In the present work, the $^{132}$Sn(d,t)$^{131}$Sn reaction (Q=-1.055 MeV) was studied in inverse kinematics at HRIBF of Oak Ridge National Laboratory. The $^{132}$Sn ISOL beam was post-accelerated to an energy of 4.39~MeV/u using the ORNL HRIBF accelerator. The beam (average intensity of $\sim$1.2e4 pps) impinged on a $\sim$250-$\mu$g/cm$^2$ deuterated polyethylene target, for approximately 4 days. Ejected tritons were detected using the Super ORRUBA array of segmented Si telescopes. Low-lying states in $^{131}$Sn were populated in the experiment. Preliminary results will be shown.
