“…This confirms the 89 assignment of 123 keV level of 131Cs, as for a cascade involving intermediate level of 89 + spin the correlation becomes isotropic. This result confirms the latest measurements of Krane [13] and previous assignment of Fechner et al [4] and Hasselgren et al [5]. The 5+ spin assignment by Sharma et al [9] is thus ruled out.…”

“…2. The liquid source material was used in these measurements and the attenuations of the cascades involving long lived 133 keV level (T 89 ns) was taken to be negligible as indicated by Fechner et al [4] from their time differential measurements. Krane [13] also considered the liquid sources free from any attenuations.…”

The electron-capture decay of t3~Ba (T 89 d) to excited levels of 13~Cs has been studied using high resolution semiconductor detectors. The presence of 1046.9 keV gamma-ray in between 1170.6 and 123.8 keV levels, in addition to 1047.6 keV gamma-ray from 1047.6 keV level to ground state of ~31Cs is confirmed through gamma-gamma coincidence measurements. The K-capture probabilities to 1047 keV, 696 keV and 620 keV levels are measured using X-gamma coincidence method. The gamma-gamma directional correlation measurements of the cascades 496-123, 240-133, 486.133, 404-216, 480 216 and 832-216 keV are carried out and spins and multipolarities of the levels and transitions involved are studied.
