On the Intensities of γ-Rays of RaC

Abstract

The intensities of γ-rays of RaC were investigated with a semi-circular focusing magnetic spectrometer and coincidence technique of G-M counters.
The efficiencies of thick radiator for γ-rays of various energies were calculated according to the experimental straggling curves obtained by White and Miliington and also taking the scattering losses into concideration. And the intensities of γ-rays were determined from the maximum heights of momentum distribution curve of Compton recoil electrons projected from a thick target of aluminium. From these values and the relative intensities of conversion electrons reported in our former paper, the internal conversion coefficients were calculated and compared with the results of former authors, and with theoretical values.
Both the intensities of γ-rays of RaC and the internal conversion coefficients obtained are in accord with the results of Ellis and Aston.
