Description

We have applied the fast timing βγγ(t) technique to remeasure lifetimes of selected states in 223Ra populated in the β- decay of 223Fr. T1/2 = 587(12) ps and 210(13)ps have been obtained for the 3/2- and 5/2- states at 50.1 and 79.7 keV, that are more accurate than the previous values of 630(70)ps and 166(55)ps, respectively. Our vertical stroke D0 vertical stroke value of 0.155(10)e.fm obtained for the K = 3/2 configuration together with the available values of vertical stroke D0 vertical stroke for the K = 1/2 and K = 5/2 parity doublet bands establish the configuration dependence of vertical stroke D0 vertical stroke at low spins in this nucleus. Results of theoretical calculations performed for 223Ra, using the quasiparticle-phonon model (QPM) with inclusion of the Coriolis coupling, reasonably well reproduce octupole correlations in this nucleus.
