Internal Conversion of Gamma-Ray Transitions in the L -Subshells

A number of internally converted γ-transitions have been investigated with high resolution β-spectrographs and the relative intensities of conversion electron lines from the three L-subshells obtained. Generalizations are made for L-conversion as related to multipole order. The magnetic transitions investigated are converted in the LI- and LIII-shells, the ratio LIIILI increasing with increasing multipole order. Less can be said about electric transitions; but L-conversion takes place mainly in the LII- and LIII-shells for the transitions studied.
