Inelastic Proton Scattering Analyses and Ambiguities in Spin–Parity Assignments of States in ¹²C

Abstract

Data from the excitation of the 13·35, 18·35, 19·20 and 19·40 MeV states in ¹²C by the inelastic scattering of protons have been analysed using a fully microscopic distorted wave approximation to determine optimal assignments from amongst the current and ambiguous J ^π; T values of each state involved. While not conclusive, the present analysis suggests the assignments of 4^-₁; 0, 2^-₂; 0, 4^-₂; 0 and 22^-₂; 1 respectively.
