Abstract: | Energy levels of the single excited 1s22s2ns (2S), 1s22s2np (2P), 1s22s2nd (2D) and 1s22s2nf (2F), n = 3-8 states for the boron isoelectronic sequence are calculated using the simple configuration Hartree-Fock method. Good agreement is obtained between our results and previous experimental and theoretical data. |
