Popis: The effect of correlation on the ${\mathit{g}}_{\mathit{J}}$ factors of ground-state and some metastable 2s- and 2p-row atoms is evaluated from experimental data and theoretical values calculated within the Hartree-Fock scheme. By taking the accurate experimental ${\mathit{g}}_{\mathit{J}}$${(}^{4}$${\mathit{S}}_{3/2}$) values of atomic nitrogen as reference, the effect is seen to amount to -1.0 ppm per unpaired 2l electron. A configuration-interaction calculation for ${\mathit{g}}_{\mathit{J}}$(N${;}^{4}$${\mathit{S}}_{3/2}$) yields a value that agrees with experiment to within 0.24 ppm. This also shows that the effect of correlation on ${\mathit{g}}_{\mathit{J}}$(N${;}^{4}$${\mathit{S}}_{3/2}$) is mainly due to core polarization and amounts to -0.94 ppm per polarizing 2p electron.
