BETA-P,-2P,-ALPHA SPECTROSCOPY OF SI-22,SI-23,SI-24 AND AL-22

In an experiment at the LISE3 facility of GANIL, we used the projectil e fragmentation of a Ar-36 primary beam at (95) MeV/nucleon to produce neutron-deficient isotopes in the Al-Si region. The selected isotopes were implanted in a detector telescope, where their decay particles w ere observed. We report here on the study of the beta p, beta 2p, and beta alpha decay of the isotopes Si-22,Si-23,Si-24 and Al-22. Beta-dec ay half-lives have been measured. The ground-state mass excess of Si-2 3 has been determined. Partial decay schemes are presented on the basi s of the transitions associated with the observed decay peaks.
