The relativistic random-phase approximation is used to calculate the excitation energies and absorption oscillator strengths for the 3s/sup 2/ /sup 1/S/sub 0/-3s3p /sup 1/P/sub 1/, -3s4p /sup 1/P/sub 1/, -3s5p /sup 1/P/sub 1/, and -3s3p /sup 3/P/sub 1/ transitions of selected elements of the magnesium isoelectronic sequence through nuclear charge Z = 92. The results are compared with previous theoretical and experimental values. The data, plotted as a function of Z/sup -1/ enable us to study deviations from the predictions of the nonrelativistic Z-expansion theory.
