INVESTIGATION OF BAND-MIXING ANOMALIES IN SM152

Multiple Coulomb-excitation measurements of absolute transition-matrix elements from β-band states in Sm152 indicate that the previously reported discrepancies with band mixing arise from a source different from that previously suggested; the matrix elements for the 2β→2, 0β→2, and 2β→0 transitions are consistent with a band-mixing parameter Z00.08, although an inconsistency remains for the 2β→4 transition. Angular correlation studies show that δ(2β→2)=-67-+54 and δ(4β→4)=-2.94-1.86+0.85. © 1969 The American Physical Society.
