Excited states in 30 Mg have been populated to ∼6h and 5 MeV excitation energy with the 14 C( 18 O,2p) reaction. Firm spin assignments for states with J > 2h have been made in this nucleus. The level scheme is compared to shell-model calculations using the Universal sd effective interaction and the Monte Carlo shell model method. Calculations employing a full sd model space fail to reproduce the observed levels. The results indicate that excitations across the N = 20 gap are required at relatively low excitation energy to achieve a description of the data. The incorporation of the f 7/2 and p 3/2 orbitals into the model space gives improved results but indicate the need for further refinement of the models to reproduce the observed spectra.
