Abstract

Conversion electron and gamma spectroscopic measurements were carried out on the 160.44d 177m Lu decay with a mini-orange electron transporter coupled to a Si(Li) detector and a large-volume HPGe detector. Conversion electron intensities and internal conversion coefficients of 32 transitions in the two nuclei were obtained by the Normalized Peak to Gamma method. Of these, many are being reported for the first time. Mixing ratios were determined for the M1 + E2 transitions of the rotational bands 7/2+[404] in 177Lu , 7/2[514] and 9/2+[624] in 177Hf populated by the isomer’s decay. The value of the rotational parameter |(g K g R )/Q 0| was calculated for all the three bands. A revised decay scheme is proposed for 177m Lu .
