The relativistic core-polarization corrected model potential energy levels and oscillator strengths are computed for highly ionized spectra of silver isoelectronic sequences from Ce XII through Ho XXI and for the W XXVIII spectrum. Calculations were performed altogether for 781 relativistic components of 5s–np, 5p–nd, 5d–nf, 4f–nd transitions with n = 5–9, and for 6s–np and 5p–ns transitions with n = 6–9. This paper presents oscillator strength values only for the 19 lowest transitions for each spectrum compared with other theoretical data available. The remaining data are available in electronic form upon request. It is demonstrated that core polarization (core-valence electron correlation) has a strong influence on oscillator strengths, not only for spectra close to the neutral end of the silver isoelectronic sequence, as believed in the past, but also for highly ionized systems.
