Measurement of disintegration rate and decay branching ratio for nuclide 192Ir with β-, EC mixing decays by using 4πβ-γ coincidence counting
- 1. Northwest Inst. of Nuclear Technology, Xi'an (China)
Description
The absolute disintegration rates for nuclide 192Ir were measured with a 4πβ-γ (HPGe) coincidence apparatus by using parameter method and extrapolation method. The final uncertainties obtained were 0.4% and 0.5% respectively for a confidence level of 99.7%. The method with which both the disintegration rate and the decay branching ratio can be measured for nuclides with β- and EC mixing decays was proposed and described. The β- branching ratio in 192Ir decays was measured being 0.9572. The final uncertainties of disintegration rates and β- decay branching ratio with this method were 1.5% and 1.8% respectively
