Abstract: | The transition energies of the 1s23d-1s2
nf (4⩽n⩽9) transitions and fine structure splittings of 1s2
nf (n⩽9) states for Sc18+ ion are calculated with the full-core plus correlation method. The quantum defect of 1s2
nf series is determined by the single-channel quantum defect theory. The energies of any highly excited states with n⩾10 for this series can be reliably predicted using the quantum defect as function of energy. Three alternative forms of the
dipole oscillator strengths for the 1s23d-1s2
nf (n⩽9) transitions of Sc18+ ion are calculated with the transition energies and wave functions obtained above. Combining the quantum defect theory with
the discrete oscillator strengths, the discrete oscillator strengths for 1s23d-1s2
nf (n > 9) transitions and the oscillator strengths densities corresponding to the bound-free transitions are obtained.
