摘要

The multiconfiguration Dirac-Fock method is used to systematically calculate the energy levels, wavelengths and oscillator strengths for transitions among the levels of the terms belonging to the 3s(2), 3s3p, 3s3d, 3s4s, 3s4p, 3s4d, 3p(2), 3p3d, 3p4s, 3p4p, 3p4d, 3d4s, 3d4p, 3d4d and 3d(2) configurations for the elements of the magnesium isoelectronic sequence from high nuclear charge Z = 53 to 58 by taking into account main correlation relativistic effects. Another wavelength region lambda = 6 - 11 angstrom from n = 3 - 4 transitions and the corresponding oscillator strengths are for the first time extensively reported. The trends of wavelengths and oscillator strengths along the isoelectronic sequence are discussed. Many strong configuration mixings and level-crossings in particular between the two states 3p3d F-3(3)0 and 3p3d D-3(3)0 in Mg-like La and Ce ions are investigated.
