Abstract

Excited states in 31S and 31P were populated in the 12C(20Ne,n) and 12C(20Ne,p) reactions, respectively, at a beam energy of 32 MeV. High spin states of positive and negative parity have been observed in 31S for the first time, and the yrast scheme of 31P has been extended. Large mirror energy differences between the first 9/2- and 13/2- states were observed, but only small differences for the first 7/2- and 11/2- levels. The significance of these observations is discussed in relation to the electromagnetic spin-orbit effect and the relative binding energy of the levels.
