keV neutron capture in zinc

Abstract

Averaged gamma ray transition strengths in 65Zn and 67Zn have been measured after neutron capture in the keV energy region. These results have been compared with calculations based on resonance parameters and a statistical neutron capture mechanism. Evidence for d-wave capture in excess of that expected is given. However because of the substantial deviation from statistical behaviour of the averaged transition strengths, it is apparent that configuration effects play a major role in the determination of partial capture cross sections.
