New gamma transitions in 193Ir from the beta decay of 193Os

The population and the mode of decay of the low-lying excited levels of 193Ir have been investigated by single and <FONT FACE=Symbol>gg</FONT> coincidence spectroscopy using 192Os enriched to 99% and several HPGe detectors. From singles spectra analysis the energies of 71 gamma rays have been determined with a better overall precision than previously, 17 of them for the first time. The energies at 1043.244(15) and 1316.628(18)keV , observed for the first time in this work, as well as some preliminary coincidence relationships, suggest that the end point energy Qbetamax(<FONT FACE=Symbol>»</FONT>1.14MeV) must be further investigated.
