Abstract

The single-neutron properties of the N = 83 nucleus Xe-137 have been studied using the Xe-136(d, p) reaction in inverse kinematics at a beam energy of 10 MeV/u. The helical-orbit spectrometer, HELIOS, at Argonne National Laboratory was used to analyze the outgoing protons, achieving an excitation-energy resolution of similar to 100 keV. Extraction of absolute cross sections, angular distributions, and spectroscopic factors has led to a more complete understanding of the single-neutron strength in Xe-137. In particular, the centroids of the vh(9/2) and vi(13/2) strengths appear to evolve through the N = 83 isotones in a manner consistent with the action of the tensor force.
