Investigation of excited levels in sup(193)Ir from the beta decay of sup(193)Os

Abstract

The excited states in 193Ir populated by the beta- decay of 193Os were investigated via gamma-gamma coincidence analysis. Three levels at 517, 563 and 621 keV, previsouly seen only in nuclear reaction studies, were observed in the present measurements; the 487 keV transition from the 849 keV level was identified, providing good evidence that the levels at 848.93 and 849.083 keV are the same. The level at 807 keV was positively identified through both the 449 and 668 keV transitions; also, there is evidence for four new levels at 880, 882, 890 and 986 keV, and several newly-found gamma transitions were identified and placed in the decay scheme.
