Structure of low-lying states in 128Ba from γ-γ angular correlations and polarization measurements
(2002) In Physical Review C - Nuclear Physics 66(2). p.243231-243237- Abstract
A study of the low-lying levels of 128Ba was performed using three clover detectors in a compact arrangement. The levels were populated by beta decay of 128La which was produced by the fusion evaporation reaction 116Sn(16O, 1p3n). γ-γ angular correlations and polarization measurements were performed. The decay properties of several low-lying states were investigated. Spin assignments were made for two states, and several E2/M1 mixing ratios were determined. The results are in good agreement with predictions of the O(6) limit of the interacting boson approximation. One of the states is unambiguously determined to be the hitherto unobserved member of the τ = 4 multiplet.
