Abstract
The half-life of Au200 has been measured to be 48.4 ± 0.3 minutes. The beta radiations emitted in the decay of Au200 have been studied by absorption in aluminum, and the gamma radiations with a multichannel scintillation spectrometer. Two beta rays with end-point energies of 2.25 ± 0.20 and 0.7 ± 0.1 Mev and respective abundance of (75 ± 3)% and (25 ± 3)% were detected. Three gamma rays with energies of 0.367, 1.23, and 1.60 Mev were observed. It was established that the 0.367- and 1.23-Mev gamma rays are in coincidence. A decay scheme for Au200 is proposed.Keywords
