Abstract

The levels of Zr93 populated in the decay of Y93 have been deduced from Ge(Li)-Ge(Li) coincidence and Ge(Li) singles -ray spectra. 22 of the 23 observed -ray transitions have been placed in a level scheme for Zr93 with 11 excited states. These results are compared with those of previous investigations. A number of corrections, clarifications, and expansions of decay schemes previously reported resulted from the use of high-resolution detectors and a mass-separated source strong enough to permit coincidence studies of the weak as well as the intense transitions. Spin-parity assignments of the Zr93 levels have been deduced using relative -ray transition rates, -decay logft values, and results of nuclear-reaction studies. Possible interpretations of some of the levels are presented, based on shell-model descriptions. [RADIOACTIVITY Y93 (from Kr93 decay); measured E, I, - coin, calculated logft.
