The Half Life of {sup 193}Osbeta-decay

In this work, the half life of the beta{sup -} decay of {sup 193}Os was measured by following the activity of 25 5 mg {sup 192}Os-enriched samples for 20-60 h after they were irradiated in the IEA-R1 reactor of IPEN-CNEN/SP. Three different transitions associated with this beta decay were analyzed,...

Description
Summary:In this work, the half life of the beta{sup -} decay of {sup 193}Os was measured by following the activity of 25 5 mg {sup 192}Os-enriched samples for 20-60 h after they were irradiated in the IEA-R1 reactor of IPEN-CNEN/SP. Three different transitions associated with this beta decay were analyzed, and the results were then processed using three different statistical methods; the resulting values were compatible with the tabulated value, with an uncertainty of the same order of magnitude.
