Wavelength and oscillator strength for 1s23s-1s2np transition of Cu26+ iojn

The non-relativistic energies of 1s23s and 1s2np (n  9) states for Cu26+ ion are calculated by using the full-core plus correlation method. Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects, we estimate the higher-order relativistic contribution and QED correction to the energy under a hydrogenic approximation. The transition energies, wavelengths and oscillator strengths for the 1s23s-1s2np transitions of this ion are calculated. The results agree with experimental available in literature data satisfactorily. By combining with quantum defect theory, our theoretical predictions on the energy and oscillator strength of this ion are extrapolated to whole energy region including continuous states.
