1. Physics

The single-neutron properties of the N = 83 nucleus {sup 137}Xe have been studied using the {sup 136}Xe(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 {approx}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 {sup 137}Xe. In particular, the centroids of the vh{sub 9/2} and vi{sub 13/2} strengths appear to evolve through the N = 83 isotones in a manner consistent with the action of the tensor force.
