Magnetic dipole and electric quadrupole hyperfine constants for V II 3d(4), 3d(3) 4s and 3d(2) 4s(2)J=1-5 states

摘要

Relativistic configuration interaction (RCI) calculations have been done for hyperfine constants and Lande g-values for 69 even parity V II states. Our results are in good agreement with the few recent experimental magnetic dipole results. We suggest that several Lande g-values need to be re-measured. Our electric quadrupole constants seem to be the first ones available. Analysis and methodology improvements include the introduction of an approximate sum rule for hyperfine constants, and a way of producing a more diagonal reference basis function set. The importance of mixing of 3d(n-1) 4s basis members with near degenerate 3d(n) or 3d(n-2) 4s(2) is emphasized.
