Hyperfine structure investigation of ScI, part II: theoretical studies of the odd configurations

Abstract

Based on the experimental hyperfine structure data given in our previous study, the multi-configuration method has been used to calculate the fine structure of the odd parity configurations 3d4s4p, 4s(2)4p and 3d(2)4p of neutral Scandium taking into account configuration interaction effects. Magnetic dipole hyperfine structure constants are analysed in the effective-operator formalism for the isotope Sc-45. Relativistic one-electron parameters of the magnetic dipole hyperfine structure a(nl)(kskl) (k(s)k(l) = 01, 10, 12) were fitted to the experimental data by a least-squares fit procedure. Theoretical predictions for the magnetic dipole hyperfine structure constants A for all levels of the three configurations are given.
