The Radioactive Decay ofCs134,Os185,Os191, andOs193

Abstract

From sources of cesium of high specific activity produced in the pile and studied in photographic magnetic spectrometers, nineteen electron conversion lines are observed. These are interpreted to show the existence of eleven gamma-rays, four of which have not been previously reported. Certain K/L ratios are measured and the resolution of the components of the beta-radiation presented. A plausible decay scheme consisting of seven levels in the resultant barium 134 nucleus is offered.
