Theoretical calculation shows that there are several magic wavelengths with the linearly polarized trapping laser. The trap depths of the optical lattice and the slope of light shift difference with different magic wavelengths are also calculated, Some of these magic wavelengths are selected and recommended as potentially suitable magic wavelengths for the optical lattice trapping laser.展开更多

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 2s^22p^62s2p^6np, the quantum defects for 2s2p^6np Rydberg series of Cu^19+ 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 Cu^19+ and Cu^20+ ions are also calculated and they excellently accord with previous experimental and calculated values.展开更多
