Polarization transfer in (p, n) reactions

Abstract

Polarization-transfer studies for (p, n) reactions with normally polarized (N-type) beams have been pursued at the Indiana University Cyclotron Facility, Bloomington, IN, since 1983. A variety of targets having values of A ranging from 2 to 90 have been studied at 0° for bombarding energies between 80 and 200 MeV. Transitions to well-resolved final states in the lighter nuclei have yielded data that lend plausibility to distorted-wave impulse approximation interpretations of intermediate-energy nucleon–nucleus reactions. Measurements on heavier nuclei have revealed interesting nuclear-structure effects at high excitation energies.
