摘要/Abstract

摘要： The transition energies, wavelengths and dipole oscillator strengths of 1s$^{2}$2p-1s$^{2}n$d ($3 \le n \le 9$) for Cr$^{21 +}$ ion are calculated. The fine structure splittings of 1s$^{2}n$d ($n \le 9$) states for this ion are also calculated. In calculating energy, we have estimated the higher-order relativistic contribution under a hydrogenic approximation. The quantum defect of Rydberg series 1s$^{2}n$d is determined according to the quantum defect theory. The results obtained in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from initial state 1s$^{2}$2p to highly excited 1s$^{2}n$d states ($n \ge 10$) and the oscillator strength density corresponding to the bound--free transitions are obtained.
