Atomic structure and transition parameters of the C-like ion K XIV

Abstract

Abstract Energy levels, lifetimes, oscillator strengths and transition probabilities for the multicharged carbon like K XIV ion have been calculated with the configuration expansion: 2s22p2, 2p4, 2s22p3p, 2s22p4p, 2s2p23s, 2s2p24s, 2s2p23d, 2s2p24d, 2s2p23p, 2s2p24p, 2s22p3s, 2s22p4s, 2s22p3d, 2s22p4d and 2s2p3. Two methods were used in the calculations: the Hartree-Fock pseudo-relativistic approach and the Thomas-Fermi-Dirac-Amaldi potential approach using the Cowan and the AUTOSTRUCTURE atomic structure codes respectively. Results have been compared with data from National Institute of Standards and Technology Atomic Spectra Database (NIST-ASD) and from other theoretical methods. Obtained new data will be important for plasma analysis in laboratories and for astrophysical modeling.
