Аннотация:The two-body model with the Hulthen potential is used to calculate the quantities characterising the vertices of the virtual decay T->d+n for the bound (T) and virtual (v) triton states. The parameters of the potential are fitted to the experimental values of the triton binding energy and the nd doublet scattering length as well as to the corresponding values obtained by solution of the Faddeev equations. The calculated results for the position of the virtual triton pole, the vertex formfactor and the vertex couplng constants for the bound and virtual states are in satisfactory agreement with three-body calculations and with the experiment. The correlation between the vertex constants and the tritium binding energy is studied.
