It is theoretically pointed out that, even between strongly correlated doubly excited states, there exist single-electron--type transitions for electron-impact excitation processes of He atoms in doubly excited states under the condition {Delta}{ital L}=0, where {ital L} is the total orbital angular momentum of the atom. The propensity rules found for the {sup 1}{ital P}{sup {ital o}}-{sup 1}{ital P}{sup {ital o}} and {sup 1}{ital D}{sup {ital e}}-{sup 1}{ital D}{sup {ital e}} double-excitation processes are also presented and discussed based on the rovibrational interpretation of the collective motion of two atomic electrons.
