An internal conversion study of the decay of193Au

The internal conversion spectrum following the decay of¹⁹³Au has been studied in the electron energy region 0.8 to 700 keV, with the use of high-resolution magnetic beta-ray spectrometers. Several not previously reported transitions have been estabblished. Multipolarities and mixing ratios have been deduced fromK/L and subshell intensity ratios, and the majority of the transitions were found to be ofM1 and/orE2 characters. A revised level scheme for¹⁹³Pt, which consistently accomodates most transitions, has been constructed. Tentative spin-parity values have been assigned to all levels.
