Study of the Excited States of ZINC-60,61.

The level structures of the nuclei ('60)Zn and ('61)Zn have been studied by means of ((tau),n(gamma)) and ((alpha),n(gamma)) reactions, respectively. Additional heavy ion induced reactions were also investigated with respect to ('60,61)Zn and other competing channels, notably ('59)Zn, ('60)Cu and ('61)Ga. Gamma singles, n-(gamma) coincidence, (gamma)-(gamma), multi-(gamma) coincidence, (gamma) and n-(gamma) angular distribution measurements were made. Limitations on excited state lifetimes were obtained from beam pulsing, electronic timing, and Doppler shift measurements. A high resolution neutron spectrum of the ('58)Ni((alpha),n)('61)Zn reaction was obtained. Attempts at other multi-particle transfer experiments have been unsuccessful. The experimental results are compared with those found elsewhere and with theoretical calculations.
