Abstract

In an experiment performed at the LISE3 facility of GANIL, we studied the decay of Al-22 produced by the fragmentation of a Ar-36 primary beam. A beta-decay half-life of T-1/2 = 91.1 +/- 0.5ms was measured. The beta-delayed one- and two-proton emission as well as beta-alpha and beta-delayed gamma-decays were measured and allowed us to establish a partial decay scheme for this nucleus. New levels were determined in the daughter nucleus Mg-22. The comparison with model calculations strongly favours a spin-parity of I-pi = 4(+) for the ground state of Al-22.
