Properties of Intruder States in ³⁴Al and ³⁴Si

Abstract

We report on two experimental results for nuclei located in the region of the N=20 island of inversion. In the first experiment, performed at GANIL, we have discovered and studied the 0 + 2 state in 34 Si and made the hypothesis that it was fed by the beta-decay of a predicted isomeric 1 + state in 34 Al. In the second experiment, performed at ISOLDE, we have studied the beta-decay of 34 Mg in order to obtain information on the structure of 34 Al and in particular the position of the isomeric 1 + state.
