Mechanisms for double-electron capture producing projectile doubly-excited states in collisions are studied. Emphasis is given to slow collisions with projectile energies of a few keV. At these impact energies the production of configurations of nonequivalent electrons is dominant. The creation of these nonequivalent electron states with originates from dielectronic processes involving electron-electron interaction. The present close-coupling calculations are compared with our recent measurements of absolute double-capture cross sections. A fairly good agreement between theory and experiment is found, especially for the total double capture as well as for the significantly populated configurations
