Neutral Currents in the 16O Nucleus

Abstract

The aim of this paper is to investigate the parity and isospin forbidden a0 decay from 16O (Jp = 1+; T = 1;Ex = 16.209MeV) to 12C(g.s.) by calculating the longitudinal AL and the irregular transverse Ab analysing powers of the reaction 15N( p, α0)12C around the 1+, Ex = 16.2MeV resonance in 16O. The range for the expected interference effect has been estimated to be AL 3.2 ×10-5 and Ab 2.3 × 10-5.
