Abstract
The structure of neutron-rich light nuclei around N=20 and 28 has been investigated at GANIL by means of in-beam gamma-spectroscopy using fragmentation reactions of 36S and 48Ca beams on a Be target. Gamma-decay of relatively high-lying excited states have been measured for the first time in nuclei around 32Mg and 44S. Level schemes are proposed and discussed for a large number of these neutron-rich nuclei around N=20 and N=28.
