Abstract
The neutron-deficient -shell nuclei are studied in the framework of the shell model with the configuration. Several "spin-gap" isomers with a half-life of an order of a second are predicted in , , , and . Among them, the state in is predicted to be an isomer which corresponds to recently observed by Nolte and Hick. It is also shown that the high-spin isomers above the proton threshold are rather stable against the proton emission.
