The Low Energy Level Structure of {sup 191}lr

Abstract

The decay of {sup 191}Pt to {sup 191}Ir has been investigated using Ge(Li)-detectors and a double focusing beta spectrometer. 35 transitions were observed and most of them were placed in a level scheme. Special attention was given to the low energy level band structure. Several multipolarity mixing ratios were determined from L-subshell ratio measurements. Using the delayed coincidence technique the half-life of the 179.05 keV level was measured to 40 {+-} 12 psec. The low level decay properties are discussed in terms of the Nilsson model with the inclusion of Coriolis coupling.
