Semiempirical calculation of oscillator strengths in multiply charged ions with an electron above clossed core

Results of calculation of dipole transitions oscillator strengths in ion spectra of potassium and cesium isoelectronic sequences are presented. The calculation was made in the framework of relativistic method of model potential using energy approach. It is shown that correction to the value of oscillator strength for a number of transitions in K-like and Cs-like ions can be quite considerable i.e. 15%
