Hindrance effects on the β moments for the 72-(0.435-MeV β-)72+ transition from the decay of Ce141

The β moments of the 72-(β-)72+ transition from the decay of Ce141 have been extracted from the available experimental data. We have obtained the following results (expressed in fm): iσ→•r→=0. 32±0.08, i r→=0.029±0.012, σ→×r→=-0. 20±0.07, iBij=-0.43±0.57, γ5ξ=0.98±0.10, and α→ξ=0.065±0.027. These re...
