摘要

The beta decays of the new isotopes exp 53 Ti and exp 59 Mn are studied. These neutron-rich isotopes have half-lives of 32.7 +- 0.9 s and 4.75 +- 0.14 s, respectively. They are produced via the exp 48 Ca( exp 7 Li,pn) exp 53 Ti and exp 48 Ca( exp 13 C,pn) exp 59 Mn reactions using beams from the Argonne National Laboratory FN Tandem Van de Graaff accelerator. Measurements of gamma singles, gamma - gamma coincidences, and beta - gamma coincidences were facilitated by a pneumatic target-transfer system (''rabbit''). Decay schemes are presented, and the measured masses will be compared with various predictions. The relevance to astrophysics is discussed. In addition, a new 8-target multiple rabbit system is described. (ERA citation 01:024994)
