Abstract: | The variational method using a multiconfiguration interaction wavefunction is carried out on the high-lying core-excited states 5P(n) (n = 1-3) and 5So(m) (m = 1-3) for the Be-like isoelectronic sequence from Z = 7 to 10, including mass polarization and relativistic corrections. Relativistic energies, oscillator strengths, wavelengths, and lifetimes are reported. The results are compared with other theoretical and experimental data in the literature. The fine structure and hyperfine structure of core-excited states for this system are also investigated. |
