K-Electron Ejection in the Beta Decay ofS35

Abstract

By means of proportional-counter pulse-height analysis, it is found that ${\mathrm{S}}^{35}$ sources emit $K$ photons of chlorine with a probability of 2.47(±0.6)×${10}^{-4\mathrm{}}$ photon/beta (the indicated error being an extreme), equivalent to a probability for $K$-hole production of 2.3(±0.7)×${10}^{-3\mathrm{}}$ $K$ hole/beta. The theory, which has about the same accuracy as the experiments, predicts 3.0×${10}^{-3\mathrm{}}$ $K$ hole/beta.
