Lifetimes of a dipole cascade in192Hg

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Lifetimes of ten states with spins between 23 and 32 have been measured in a cascade of dipole transitions in192Hg using the Doppler-shift recoil-distance method. Average reduced transition probabilities, deduced from the lifetimes, are B(M1)≈0.01 and 1.1µ 2 n in the lower and higher spin region of the cascade, respectively, and B(E2)≈0.13 (eb)2. The jump in the B(M1) values can be explained by different multi-quasiparticle configurations in the lower and higher spin regions of the band.
