geometry.5) The states with Rg+(2P1/2) ion-core configuration

are shown by dashed lines. The dark circles show positions

of expected strong interactions of the diabatic potentials. The

only Ω = 1/2 components correlating to X(2P3/2) have been

included in the drawing because they are more important

than Ω = 3/2 components.
