Different contributions to radiative stabilization in Ne{sup 10+}+He collisions at projectile energies of 10 and 150 keV are studied. For both energies, radiative stabilization is found to be equal to {approx_equal}0.3 when referred to the total double capture. In Ne{sup 10+}+He collisions doubly excited states 3{ital lnl}{sup {prime}} and 4{ital lnl}{sup {prime}} ({ital n}{ge}4) are either produced by uncorrelated two-electron transitions or by dielectronic mechanisms due to electron-electron interaction. A strong contribution ({approx_equal}0.15) to the stabilization follows from the decay of near-equivalent electrons 3{ital lnl}{sup {prime}} and 4{ital lnl}{sup {prime}}({ital n}=4,5). Another major contribution (0.10{endash}0.25) to stabilization is due to the decay of configurations 3{ital lnl}{sup {prime}} ({ital n}{ge}6) of nonequivalent electrons produced by the dielectronic process of autoexcitation. A small contribution is found to be due to the configurations 3{ital lnl}{sup {prime}} ({ital n}{approx_gt}9) created by dielectronic phenomena in the postcollisional and asymptotic regions ({approx_equal}0.04). {copyright} {ital 1996 The American Physical Society.}
