Abstract

Beta-decay half-lives have been measured for eight neutron-rich isotopes produced in the fragmentation of 11.4-GeV Ar40 on Be9. The experiment used a new measurement technique designed to observe very short half-lives. The previously unknown half-lives of O22 (910 ± 350 ms) and Al32 (35 ± 5 ms) have been obtained, as well as six known half-lives to provide a check of the procedure.
