Neutron Transfer Reactions with $^{126,128}$Sn Rare Isotope Beams

ORAL

Abstract

Neutron transfer reactions with $^{132}$Sn beams have identified robust single-neutron excitations in $^{133}$Sn above the N=82 shell closure. A similar pattern has been observed in $^{131}$Sn, with potential implications for r-process abundances. To extend the systematics of single-neutron excitations in neutron-rich Sn nuclei, the (d,p) reactions has been studied with beams of $^{126,128}$Sn. Measurements were performed at the HRIBF at ORNL with arrays of charged particle detectors including the Super ORRUBA highly-segmented silicon detector array. Preliminary results from these studies, and in comparison with measurements with stable $^{124}$Sn and earlier $^{130,132}$Sn beams will be presented.
