Transition energies, wavelengths, oscillator strengths and transition probabilities between 1s2, 1sns and 1snp (2⩽n⩽9) states for He-like Silicon

Multiconfiguration Hartree-Fock calculations with Breit-Pauli relativistic corrections are reported for electric dipole transition (E1) energies, wavelengths, weighted oscillator strengths and transition probabilities between all of the 1s2, 1sns and 1snp (2⩽n⩽9) states for He-like silicon. The results are found to compare very well with available other results except Δn=0 due to differences in the calculated excitation energies.
