Non-normal parity states in A = 15, 14 and 13 nuclei

Abstract

Abstract Shell-model calculations for the non-normal parity states of A = 15, 14 and 13 nuclei are carried out within the framework of the 1p n-1 (2s, 1d) and 1s 3 1p n+1 configurations where n = A − 4. The matrix elements of the two-body interactions between the 1p nucleons are fixed to be those determined by Cohen and Kurath from a least-squares fit. In addition, the two-body interactions between inequivalent nucleons are assumed to arise from a central force. The results for energy levels, transition probabilities and spectroscopic factors are in good agreement with experiment.
