Theory of the X-Ray LinesLL−LM

The quantum theory is applied to the calculation of the x-ray line structure to be expected from transitions, between doubly-ionized states, of type $\mathrm{LL}$ to $\mathrm{LM}$ (we indicate missing electrons). Energy levels and wave-lengths are calculated for the silver atom according to usual ideas of atomic structure. For the calculation of the relative intensities it is assumed that the excitations of the initial ($\mathrm{LL}$) levels arise from internal conversion of $K$ excitation energy. The predicted structure agrees quite satisfactorily with the structure observed by C. J. Burbank and described in the preceding paper.
