摘要: Ca41, a nuclide decaying by orbital electron capture, was again identified and its half life measured. The activity of the source, highly irradiated sample calcium carbonate, had decayed for 10 years so that competing activities were non-existent. measurement made with gas-flow proportional counter well-determined characteristics. A value 7.5 plus or minus 1.1 x 104 obtained.
