Abstract

We have begun a program to measure (d,p) reactions on neutron-rich nuclei, probing the single-particle states near the N = 50 and N = 82 closed shells. We have measured the neutron transfer on two N = 50 isotones, ⁸²Ge and ⁸⁴Se, at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. We have also performed a test measurement of transfer on ¹²⁴Sn to develop the techniques to study the ²H(^130,132Sn, p)^131,133Sn reactions. Preliminary results for ⁸⁵Se are consistent with 5/2⁺ ground state and 1/2⁺ first excited state assignments, and the successful measurement of the ²H(¹²⁴Sn,p)¹²⁵Sn reaction demonstrates the feasibility to measure the (d,p) reaction with neutron-rich ^130,132Sn beams.
