Systematical Study on Ground-State Ionization Potentials for Boron and Carbon Isoelectronic Sequences with Z=6-42

摘要

The multi-configuration Dirac-Fock method is used in this work to calculate ground-state ionization potentialsof Boron and Carbon isoelectronic sequences from Z=6 to Z=42.And the contribution of relativistic corrections,nuclear volume effect, Breit and QED effects to the results is discussed in the calculation.The results are comparedwith the scanty existing theoretical and experimental data in the literature and good agreements are achieved.Thenanalytical expressions of Ionization potential along Boron and Carbon isoelectronic sequences are obtained.
