Multiconfiguration Dirac–Fock (MCDF) calculations are used to interpret the field shift contributions to isotope shifts of Sm I in visible and near-UV transition lines. The investigated lines correspond to the transitions between the ground configuration 4 f 6 6 s 2 and the excited configurations 4 f 6 6 s 6 p and 4 f 5 5 d 6 s 2 . For the 6 s 6 p transition the field shift is negative as a result of the reduced 6 s electron occupation, whereas for the 4 f 5 d transition the field shift is positive because of the decreased screening of 6 s and inner-shell electrons. MCDF calculations for the electron charge density at the origin that include the configuration mixing effect agree well with the electronic factor ratios derived from experimental data with the exception of a few cases of 6 s 6 p transitions.
