Measurements of neutron-rich nuclei with (d,p) reactions at HRIBF

Spectroscopic information about nuclei around the closed shells at N=50 and N=82 is important in constraining the shell model and understanding the production of heavy nuclei in supernovae. The advent of beams of fission fragments resulting from proton induced fission of a uranium carbide target at HRIBF opens up the possibility to make spectroscopic measurements of neutron-rich beams in this region. We have a program of measurements based at the HRIBF of ORNL using the (d,p) reaction mechanism in inverse kinematics to extract spectroscopic information about both the ground state and low-lying excited states of neutron-rich nuclei. Results from our recent test experiment using a stable beam of 124Sn to develop techniques for measuring 132Sn(d,p) will be presented. These results will be shown in comparison to data from the same reaction performed in normal kinematics on a stable 124Sn target in the 1970's and to DWBA calculations. I will also show results for 82Ge(d,p).
