The approximate variants frequently employed to construct the vertex part of the amplitude of the (..cap alpha.., 2..cap alpha..) reaction and involving replacement of the ..cap alpha cap alpha.. amplitude off the mass shell by an amplitude on the mass shell are discussed. With the reactions /sup 6/Li(..cap alpha.., 2..cap alpha..) d and /sup 12/C(..cap alpha.., 2..cap alpha..)/sup 8/Be(g.s.) as examples, it is shown that at low energies (E<100 MeV) the off-shell effect is appreciable, and consequently neither of these approximate variants can be used for a systematic investigation of the (..cap alpha.., 2..cap alpha..) reaction.
