BETA-DELAYED PROTON SPECTROSCOPY OF SI-24

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 t he isotope Si-24. The beta decay half-life of Si-24 has been determine d to be T-1/2 = (140 +/- 8) ms, in agreement with earlier measurements . In addition to the decay of the isobaric analog state, several proto n peaks are observed for the first time allowing to identify most of t he Gamow-Teller transitions to unbound states and to present a partial decay scheme for Si-24. These results are compared with shell-model p redictions. (C) 1998 Elsevier Science B.V.
