Abstract
The level structure of 160Dy has been investigated from the decay of 160Tb (72.4d). Single gamma-gamma coincidence and fast-slow delayed coincidence systems have been used. Thirty seven gamma-ray lines could be identified and fitted in a proposed level structure of 160Dy. The positions of previously doubted transitions at energies of 98.0, 203.1, 420.3 and 1048.9 keV are confirmed. The half life time of the 86.6 keV level is found to be 2.07 +-10 nsec, and the reduced transition probability is calculated as:
[0.96+- 0.05e^2 x 10^-48 cm^2]
