Lifetime Measurements in $^{182,186}$Pt}

Abstract

Lifetimes in the yrast bands of the nuclei $^{182,186}$Pt have been measured using the Doppler-shift Recoil Distance technique. The results in both cases {\em viz.} a sharp increase in B(E2) values at very low spins, may be interpreted as resulting from a mixing between two bands of different quadrupole deformations.
