Shape coexistence and the \mth{N=20} shell closure far from stability by inelastic scattering
Following mass measurements in
the region and , we
have studied inelastic nuclear scattering
for the nuclei Si, Al and Mg.
No evidence for a low-lying shape isomeric
0 state was found in Si,
and an upper limit for the population cross-section
could be established, rendering its existence very unlikely.
A new transition was found in
Al, that is a good candidate for a 2p-2h state
and therefore a determination of the 2p-2h gap at .
Inelastic nuclear scattering strongly excites 3 states,
as seen in Si.
A strong transition was found in Mg that should
correspond to the first 3 in this nucleus, lying
very low as compared to theory and systematics
in this region
