Electron capture processes in collisions between Mg (6(2)S(1/2)) atoms and Na+(S-1(0)) ions in the 0.10-4.00 keV energy range
The fluorescence of excited species formed in collisions between neutral magnesium atoms and sodium ions has been studied experimentally using a crossed ion-atom beam technique. The only emission detected corresponded to the Na(3(2)P(3/2,3/2))-->Na(3(2)S(1/2)) decay of neutral Na atoms formed by electron capture. Its strength has permitted to resolve it into its J = 1/2 and J = 3/2 states, and for the latter the M-j magnetic states have also been separated, cross-section dependence on collision energy or branching ratio being given for all of them.
