Decay of ¹²⁹Sb

Abstract

The radiations emitted in the decay of ¹²⁹Sb have been investigated with application of Ge(Li), Si(Li) and Nal detectors. From various coincidence studies on these transitions, it is concluded that excited levels are populated at 105.5, 180.8, 464.9, 544.7, 634.0, 760.1, 812.8, 966.6, 1228.3, 1281.3, 1317.5, 1599.0, 1633.0, 1654.6, 1727.0, 1736.5, 1752.6, 1842.8, 1870.3, 2070.1, 2085.3, 2113.0 and 2133.2 keV.
The spin-parity values are tentatively assigned for low-lying levels. The results are compared with other odd-mass tellurium nuclei.
