Konversionskoeffizienten von γ-Übergängen in²⁰⁴Pb

Abstract

Two semiconductor detectors with known efficiencies were employed to measure simultaneously the intensities of the γ-rays and the conversion electrons which are emitted by a mixture of²⁰⁴Bi and^204mPb in radioactive equilibrium and by pure^204mPb. Conversion coefficients, conversion ratios and also the relative intensities of many transitions in²⁰⁴Pb were obtained. Informations about transition multipolarities are deduced. Some conversion coefficients and conversion ratios which are measured with good precision are used to check theoretical values.
