LOW-SPIN STATES OF ZN-66 EXCITED IN THE GA-66(BETA-66 DECAY(EPSILON)ZN)

Gamma-rays from the Ga-66(beta+ + epsilon)Zn-66 decay have been invest igated with a Ge(Li) spectrometer in a Compton-suppression shield. In preceding work the energies of 34 strong fines had been obtained with very high precision. By internal calibration the energies of many othe r lines observed in the present work, and thus of most excitation ener gies, could also be measured with good accuracy. Tbe 141 observed tran sitions have been placed in a Zn-66 level scheme containing 33 states. Additional new information has been obtained on gamma-ray branching r atios, log ft values, spins and parities.
