Abstract

γ-rays from the decay of a new isotope 166Ta(T12 = 32 ± 3 sec) have been studied singly and in two-parameter coincidence. Sources of 166Ta were prepared by the thermalization and transport of recoil products from the 159Tb(16O, 9n)166Ta reaction by means of a helium-jet system. Spectrum multiscaling spectroscopy provided accurate half-life information. Rotational levels of the ground-state, β- and γ-vibrational bands of 166Hf have been observed and a decay scheme with deduced branching ratios and log ft values is proposed.
