Аннотация:In the framework of the two-body Hulthen potential model quantities have been calculated related to the virtual decay T -> d + n of triton in the bound (T) and virtual (v) states.
The potential parameters were fitted to the experimental values of the triton binding energy and doublet scattering length and also to the corresponding values obtained from the solution of Faddeev equations. The results of calculation of the virtual triton pole position, the vertex form factor and the vertex coupling constants for T and v are in reasonable agreement with the three-body calculation results and with the experimental data. The correlations between the vertex constants for T and v states and the triton binding energy are obtained and discussed.
