Internal Conversion in theLI-Shell

Analytical expressions obtained by Goertzel and Rose for the internal conversion of $\gamma$-radiation have been simplified from a computational viewpoint for the $L$-shell. Complex expressions involving gamma-functions and hypergeometric functions are simplified and reduced, in several cases, to algebraic expressions. Numerical calculations have been carried out for the $L_I$-shell, for electric dipole, electric quadrupole and magnetic dipole radiation.
