Jy. Chesnel et al., RADIATIVE STABILIZATION FOLLOWING DOUBLE-ELECTRON CAPTURE IN SLOW NE10++HE COLLISIONS, Physical review. A, 58(4), 1998, pp. 2935-2943
Individual contributions to radiative stabilization in Ne10+ +He colli
sions were studied at projectile energies from 1 to 150 keV. In these
collisions doubly excited states 3lnl' and 4lnl' (n greater than or eq
ual to 4) can be produced by uncorrelated two-electron transitions or
by dielectronic processes caused by the electron-electron interaction.
Compared to our previous study of stabilization, we extended the proj
ectile-energy range down to 1 keV and the present analysis is based en
tirely on experimental data. Radiative stabilization was evaluated by
combining our recent results for Auger decay cross sections with avail
able radiative and nonradiative branching ratios. The total amount of
radiative stabilization was found to be nearly constant (approximate t
o 0.35) within the studied energy range. However, the individual contr
ibutions to stabilization were found to change significantly. At 1 keV
the major contribution to stabilization is shown to be due to the dec
ay of the nonequivalent electron configurations 3lnl' (n greater than
or equal to 6) produced during the collision by the dielectronic proce
ss of autoexcitation. [S1050-2947(98)08010-X].
