ElectronicgFactors of the Low Levels of Ni I

Electronic $g$ factors have been obtained for the seven lowest levels in Ni i by means of the atomic-beam magnetic-resonance technique. The results, in order of increasing excitation energy, are ${}_{}{}^3{}_{}{}^{}F_4^{}{}_{}{}^{}$, 1.24968(3); ${}_{}{}^3{}_{}{}^{}F_3^{}{}_{}{}^{}$, 1.08285(3); ${}_{}{}^3{}_{}{}^{}F_2^{}{}_{}{}^{}$, 0.66954(3); ${}_{}{}^3{}_{}{}^{}D_3^{}{}_{}{}^{}$, 1.33358(3); ${}_{}{}^3{}_{}{}^{}D_2^{}{}_{}{}^{}$, 1.15106(3); ${}_{}{}^3{}_{}{}^{}D_1^{}{}_{}{}^{}$, 0.49804(2); and ${}_{}{}^1{}_{}{}^{}D_2^{}{}_{}{}^{}$, 1.01297(7). A re-analysis of the atomic spectrum involving configuration interaction with intermediate coupling has resulted in an improved set of parameters. The $g$ values so computed are compared with the experimental results.
