摘要
Different contributions to radiative stabilization in Ne10++He collisions at projectile energies of 10 and 150 keV are studied. For both energies, radiative stabilization is found to be equal to approximate to 0.3 when referred to the total double capture. In Ne10++He collisions doubly excited states 3lnl' and 41nl' (n greater than or equal to 4) are either produced by uncorrelated two-electron transitions or by dielectronic mechanisms due to electron-electron interaction. A strong contribution (approximate to 0.15) to the stabilization follows from the decay of near-equivalent electrons 3lnl' and 41nl'(n=4,5). Another major contribution (0.10-0.25) to stabilization is due to the decay of configurations 3lnl' (n greater than or equal to 6) of nonequivalent electrons produced by the dielectronic process of autoexcitation. A small contribution is found to be due to the configurations 3lnl' (n>9) created by dielectronic phenomena in the postcollisional and asymptotic regions (approximate to 0.04).
