Abstract

We report experimental angular differential cross sections for one-electron capture in

{Ar}^{6 +}

-He collisions at very low energies (1.6–13 eV/u). The cross sections show an expectedly high population of core-excited states of

{Ar}^{5 +}

. An alternative mechanism for enhanced capture excitation through configuration interaction is proposed.
