(a) Ground state energy; (b) transition probabilities of E2 in Babushkin gauge; (c) transition probabilities of E2 in Coulomb gauge; (d) transition probabilities of M1. MCDHF models: VV (valence in 2p), 1SCVVV (valence correlation in 2p and core–valence correlation between 1s and 2p), 2SCVVV (valence correlation in 2p and core–valence correlation between 2s and 2p), 1S2SCVVV (valence correlation in 2p and core–valence correlation between 1s/2s and 2p), CCCVVV (valence correlation in 2p and core–valence correlation between 1s/2s and 2p, core–core correlation between 1s and 2s). RCI models: 1SCV + CC (wave functions from 1SCVVV and configuration from CCCVVV), 2SCV + CC (wave functions from 2SCVVV and configuration from CCCVVV), 1S2SCV + CC (wave functions from 1S2SCVVV and configuration from CCCVVV). Breit interaction and QED effects are out of consideration in the calculation.
