title: [Wavelengths and oscillator strengths of transitions 4s2-4s4p,4s4p-4s4d in ions from RbVIII--NbXII].
abstract: In this paper, we have calculated the energy levels of configurations 4s2,4s4p,4s4d in ions from RbVIII-NbXII by HXR method. By analyzing variation of differences between the experimental and theoretical energies with Zc along the zinc isoelectronic sequence, we put forward a new formula. Using this formula and the FORTRAN program designed by us, we calculated the energy levels of the configurations mentioned above by generalized-lests-square-fit (GLSF) method. Also, the wavelengths and the corresponding oscillator strengths of transitions 4s2-4s4p,4s4p-4s4d are given here too.
