Abstract:

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 results show that the β-moments ratio Λ(=α→ξi r→) agrees with the theoretical estimation of Fujita-Eichler Λ=2.36, and that the β moments are strongly reduced with respect to a conventional pairing model. In addition, the value of the spin-flip γ moment 1g72i r→2f72γ, measured in the (e,e′p) reaction through the isobaric-analog state in La139, is inconsistent with the present analysis. © 1974 The American Physical Society.
