Abstract

The Zr91(p,t) reaction has been studied at a proton energy of 31 MeV. Tritons were detected in a magnetic spectrograph yielding a resolution of 18 keV. Angular distributions for levels up to 2.75 MeV of excitation in Zr89 are compared to two-nucleon-transfer distorted-wave Born-approximation calculations and analyzed in terms of the mixed L transfers allowed from a nonzero-spin target. Two types of neutron configurations are observed to be populated in Zr89 by this reaction: single-hole states and one-particle, two-hole states.
