Abstract:
A simple general analytical formula is obtained for autoionization decay rates in parabolic quantum numbers for highly excited atomic states. The formula is applicable for atomic transitions without change of principle quantum nunbers (Delta n=0 transitions). A quasiclassical approach for an electron motion in Coulomb field as well as for Clebsh-Gordan coefficient is used for justification of the formula. The results obtained are of universal type applicable for a description of autoionization decay rates in arbitrary ions with complex cores.
