Spectroscopic factors provide unique information on the structure of nuclei, and can be probed by direct reactions. Medium-energy knock-out reactions were the first direct reactions to be applied to the study of exotic nuclei about ten years ago.

The results of the IS530 experiment at ISOLDE revealed new information concerning several nuclei close to the N~20 'Island of Inversion' – 34Mg, 34Al, 34Si. The half-life of 34Mg was found to be three times larger than the adopted value (63(1) ms instead of 20(10) ms). The beta-gamma spectroscopy of 34Mg performed in this experiment for the first time led to the first experimental level scheme...
