Level structure of 124Te

The level structure of 124Te has been investigated by studying gamma rays emitted following the beta decay of 124Sb to the excited states of 124Te. The intensities of 70 gamma rays observed in this decay have been measured with a better precision than known earlier. The existence of the gamma rays with energies of 1248.62 and 1731.4 keV has been confirmed, whereas the 159.4, 185.4, 385.9, 476.6, 498.4, 553.8, 997.0, 1163.2, 1388.7, 1505.6, 1557, 1950.4, 2151.5 and 2274.0 keV gamma transitions reported earlier have not been observed in the present investigations. The gamma-gamma angular correlation measurements for nine cascades populated in this decay have been done out of which 791-(646)-603 keV cascade has been attempted for the first time. From these measurements, the multipole admixtures in the 714, 723, 791, 968, 1045, 1368, 1691 and 2091 keV transitions have been obtained. These angular correlation studies have enabled us to assign 2+ and 3- characters to the levels at 2039.5 and 2694.0 keV respectively. (author)
