Abstract
The decay characteristics of 19 min126mSb have been studied using Ge(Li) and scintillation spectrometers. The sources of126mSb were obtained by the (n, p) reaction on enriched126Te. The gamma rays of energies 414.4±0.3, 666.7±0.5 and 696.1±0.5 keV were found decaying with a half-life of 19 min. The study of beta spectra employing an anthracene crystal yielded two beta groups with end-point energies of 1.9±0.15 and 2.5±0.15 MeV. The results of singles and coincidence measurements have been incorporated into a decay scheme with excited states of126Te at 666.7, 1,362.8 and 1,777.2 keV.
