Abstract

The single-neutron properties of the N=83 nucleus 137Xe have been studied using the 136Xe(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 ∼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 137Xe. In particular, the centroids of the νh9/2 and νi13/2 strengths appear to evolve through the N=83 isotones in a manner consistent with the action of the tensor force. © 2011 American Physical Society.
