The Energies of theγ−RaysfromSb122,Cd115,Ir192,Mn54,Zn65, andCo60

Abstract

The energies of the $\gamma -\mathrm{r}\mathrm{a}\mathrm{y}\mathrm{s}$ emitted in the disintegration of some radioelements have been determined by means of a magnetic spectrograph. The results may be summarized as follows: The quantum energies were obtained from the end points of distributions in momentum of Compton secondaries arising from the several $\gamma -\mathrm{r}\mathrm{a}\mathrm{y}\mathrm{s}$. Qualitative results obtained from observations on several other $\gamma -\mathrm{r}\mathrm{a}\mathrm{y}$ emitters are briefly discussed.
