Abstract
The ..beta.. decays of the new isotopes /sup 53/Ti and /sup 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 /sup 48/Ca(/sup 7/Li,pn)/sup 53/Ti and /sup 48/Ca(/sup 13/C,pn)/sup 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.
