Abstract:
Based on systematic calculations using a combined relativistic
configuration interaction and a many-body perturbation theory (MBPT)
approach, we provide a complete and consistent data set for 46 levels
belonging to the 2s22p2, 2s2p3, 2p4, 2s22p3s, 2s22p3p, and
2s22p3d configurations in C-like ions with 13≤Z≤36. The data set
includes energy levels as well as electric dipole, magnetic dipole,
electric quadrupole, and magnetic quadrupole transition properties.
Extensive comparisons with available observed and calculated results
are made and indicate that the present MBPT calculations are highly
accurate. The present data set can be used reliably for many purposes,
such as the line identification of observed spectra, and modeling and
diagnostics of astrophysical and fusion plasmas.
