Abstract  We report on the calculations of transition wavelengths and weighted oscillator strengths for 2s22p6-2s2p6np (4 ≤ n ≤ 20) electric dipole (E1) transitions of Cu19+ ion. The flexible atomic code (FAC) has been adopted for the calculations. Comparisons are made with the experimental data available, showing that the present results for 4 ≤ n ≤ 6 are more accurate than the previous calculated values. Furthermore, combining the quantum defect theory (QDT) with the transition energies of 2s22p6-2s2p6np, the quantum defects for 2s2p6np Rydberg series of Cu19+ ion are determined. In addition, the energies of any highly excited states (n > 20) for this series can be reliably predicted using the QDT and the given quantum defects. The ionization energies for Cu19+ and Cu20+ ions are also calculated and they excellently accord with previous experimental and calculated values.
