Double-electron excitation processes to (2[ital l],3[ital l][prime]) and (3[ital l],3[ital l][prime]) manifolds of He atoms by multiply-charged-ion impact have been theoretically investigated using a close-coupling method at the (1--10)-MeV/u energy regime. Hyperspherical wave functions are adopted to take full account of strongly correlated motion of two atomic electrons in He. For the excitation processes to the (2[ital l],3[ital l][prime]) manifold, the cross sections to the [sup 1][ital D[ital e]] states show the most rapid increase as projectile charge [ital Z][sub [ital p]] increases, while that to the [sup 1][ital P[ital o]] states indicate the slowest. For the 3[ital l]3[ital l][prime] excitation processes, the cross sections to the [sup 1][ital D[ital e]] and [sup 1][ital P[ital e]] states increase at almost the same rate. It is found that the isomorphism of the charge-density plots of the channel wave functions between the initial and final states governs collision dynamics in direct double-electron excitation processes when incident multiply charged ions strongly interact with the target He atoms.
