Internal Conversion in theLandMSubshells

The relative internal conversion of electric and magnetic transitions in the $L$ and $M$ subshells has been calculated nonrelativistically with neglect of screening. In the approximations employed, the relative conversion coefficients are functions of the parameter $\frac{Z^2}{\hslash \omega }$, where $Z$ is the atomic number, and $\hslash \omega$ the nuclear transition energy. For the $L$ shell, these quantities have been evaluated over the entire range of practical interest, while for simplicity, the $M$ shell has been considered only for vanishing electron momentum. Results are given for transitions of multipole order 1 through 5.
