Electric dipole, quadrupole, and magnetic dipole transition probabilities of ions isoelectronic to the first-row atoms, Li through F

Abstract

Theoretical wavelengths, oscillator strengths, line strengths, and transition probabilities for the E1, M1, and E2 transitions among states with 2 s n 2 p m configurations are presented for ions isoelectronic to the first-row atoms (Li through F). All ions up to Zn ( Z = 30) and representative ions for Z > 30 are included. The multiconfiguration Dirac-Fock technique was used to calculate necessary energy levels and wave functions. All configurations within the n = 2 complex are included to account for electron correlations and intermediate coupling. In addition to relativistic effects arising from the Dirac Hamiltonian and the Breit operator, we included the Lamb shifts of the 1s 1 2 , 2s 1 2 , and 2p 1 2 electrons.
