Conversion coefficients and yrast state spins in 180Os

Abstract

Internal conversion coefficients of transitions in 180Os have been measured using a superconducting, solenoidal electron spectrometer, operated in the lens mode. The high energy resolution and efficiency allow a precise measurement of the conversion coefficients of the 528 keV yrast transition. The values obtained, αK = 0.015(2), αL = 0.004(1) define pure E2 multipolarity. Taken with the measured γ-ray angular distribution, the conversion coefficient leads to an unambiguous assignment of 16+ → 14+ for the 528 keV transition. Show more
