Baryshnikov A.G., Blokhintsev L.D., Narodetskii I.M.
The vertex constants for the virtual decays α—>T +N and a—>d -\-d are calculated by solving the integral equations for four nucleons. The vertex constants in a model with separable spin-dependent Yamaguchi potential are G 2aTy — 17.5 ±0.9 F and G 2add = 36.7 ± 16.7 F.
