Energies, expectation values, fine structures and hyperfine structures of the ground state and excited states for boron

摘要: The 1s 22s 22p 2P ground state and the 2 np (n = 3, 4) 2P, 23s 2S, 22s2p 4P, 2L (L S, P, D), 22s2p3s 4Po, 22s2p3p 4S, 3 4S o, 2Lo D) excited states of boron are calculated using Rayleigh-Ritz variational method with multiconfiguration interaction wave functions. Energies, expectation values such as electron density at nucleus ρ(0) radial moments 〈r n 〉, fine-structure splittings calculated. Hyperfine structure parameters magnetic coupling constants these also present results in good agreement theoretical experimental data available literature should provide valuable reference for future calculations measurements.
