Abstract
Among proton-rich unstable nuclei on the light proton drip-line, nuclear structure of {sup 21}Mg, {sup 17}Ne, {sup 13}O, {sup 11}N and {sup 9}C have been investigated by the three-neutron pick-up reaction ({sup 3}He,{sup 6}He). The angular distributions measured for this reaction have shown a characteristic feature of a transferred angular-momentum (L) dependence, which provides spin-parity assignments for the new levels in these nuclei. Here, the results on the nuclear structure of {sup 17}Ne and {sup 11}N are reported. The nucleus {sup 17}Ne we almost unknown before, except that the mass excess had been determined and a few states had been suggested. Many T = 3/2 states were known in the other three members ({sup 17}N, {sup 17}O and {sup 17}F). Thus, the inclusion of the data on {sup 17}Ne levels has enabled an extensive analysis in terms of the Isobaric Multiplet Mass Equation (IMME) for several excited state quartets. This is the first report on such an extensive analysis in the same mass ststem for a wide range in excitation energy. The {sup 11}N nucleus was investigated to learn about the structure of A 11 system. This mass has been intensively studied, specially because of the halo structure observed in
