Oscillator Strengths for 2s~2-2p~2 P Transitions of the Lithium Isoelectronic Sequence from NaIX to CaⅩⅧ

The nonrelativistic dipole-length,-velocity and-acceleration absorption oscillator strengths for the 1s~22s-1s~22p transitions of the lithium isoelectronic sequence from Z=11 to 20 are calculated by using the energies and themulticonfiguration interaction wave functions obtained from a full core plus correlation(FCPC)method.In most cases,the agreement between the oscillator strengths values from the length and velocity formula is up to four or five digit.Our results are also in good agreement with previous theoretical data available in the literature.
