Abstract

The electron-capture decay of131Ba (T 1/2=11.7 d) to excited levels of131Cs 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 of131Cs is confirmed through gamma-gamma coincidence measurements. TheK-capture probabilities to 1047 keV, 696 keV and 620 keV levels are measured usingX-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.
