We have calculated the 3s{sup 2}{sup 1}S{sub 0}-3s3p{sup 1,3}P{sub 1} transition energies for neutral magnesium and Mg-like Ar{sup 6+}, Cu{sup 17+}, Kr{sup 24+}, and Mo{sup 30+} using the relativistic configuration-interaction (CI) method. These calculations are based on the relativistic no-pair Hamiltonian which includes Coulomb and retarded Breit interactions and employ finite B-spline basis functions. Quantum electrodynamic and mass polarization corrections are also calculated. For Mg-like ions studied here, intravalence correlations are treated exactly by saturating the basis with all configurations that arise from valence-valence excitations. Contributions from core polarization are also calculated with large-scale CI expansions by including dominant configurations from core-valence excitations. Agreement between theory and experiment are good for all the Mg-like ions studied here. {copyright} {ital 1997} {ital The American Physical Society}
