  Widths of $KL_{2,3}$ atomic levels for Ca, Fe, Zn has been calculated in a
fully-relativistic way using the extensive multiconfiguration Dirac-Fock and
modified Dirac-Hartree-Slater calculations. The study of de-excitation of the
$K^{-1}L_{2,3}^{-1}$ hole state has been presented. Additionally, the
approximation to $KL_{2,3}$ level widths has been examined.
