Investigation of Band-Mixing Anomalies inSm152

Multiple Coulomb-excitation measurements of absolute transition-matrix elements from $\beta$-band states in ${\mathrm{Sm}}^{152}$ indicate that the previously reported discrepancies with band mixing arise from a source different from that previously suggested; the matrix elements for the $2_{\beta }\to 2$, $0_{\beta }\to 2$, and $2_{\beta }\to 0$ transitions are consistent with a band-mixing parameter $Z_0\simeq 0.08$, although an inconsistency remains for the $2_{\beta }\to 4$ transition. Angular correlation studies show that $\delta (2_{\beta }\to 2)=-{67}_{-\infty }^{+54\mathrm{}}$ and $\delta (4_{\beta }\to 4)=-{2.94}_{-1.86\mathrm{}}^{+0.85\mathrm{}}$.
