Title: Neutron single-particle strength outside the N = 50 core

Abstract

The single-neutron properties of N = 51 nuclei have been studied with the (d, p) and (alpha,He-3) reactions, at beam energies of 15 and 50 MeV respectively, on Sr-88, Zr-90, and Mo-92 targets. The light reaction products were momentum analyzed using a conventional magnetic spectrometer. Additionally, the H-2(Kr-86, p) rea(c)tion was measured at a beam energy of 10 MeV/u, where outgoing light ions were analyzed using a helical-orbit spectrometer. Absolute cross sections and angular distributions corresponding to the population of different final states in the heavy product were obtained for each reaction. Spectroscopic factors were extracted and centroids of the single-particle strength were deduced. The observations appear consistent with calculations based on an evolution of single-particle structure driven by the nucleon-nucleon forces acting between valence protons and neutrons.
