Abstract:
Large-scale self-consistent multiconfiguration Dirac-Hartree-Fock
(MCDHF) and relativistic configuration interaction (RCI) calculations
are reported for the n≤6 levels in Be-like ions from BII to NeVII.
Effects from electron correlation are taken into account by means of
large expansions in terms of a basis of configuration state functions,
and a complete and accurate data set of excitation energies;
lifetimes; wavelengths; electric dipole, magnetic dipole, electric
quadrupole, and magnetic quadrupole line strengths; transition rates;
and oscillator strengths for these levels is provided for each ion.
Comparisons are made with available experimental and theoretical
results. The uncertainty of excitation energies is assessed to be
0.01% on average, which makes it possible to find and rule out
misidentifications and aid new line identifications involving
high-lying levels in astrophysical spectra. The complete data set is
also useful for modeling and diagnosing astrophysical plasmas.
