Reaction rate for radiative 3He3H capture
In the framework of the modified potential cluster model with forbidden states the radiation 3He3H-capture at low and astrophysical energies is considered. It is shown that on the basis of potentials which are coordinated with scattering phase shifts and energy of the bound state it is possible to describe the available experimental data. The astrophysical S -factor and the reaction rate were calculated on the basis of the obtained total cross-sections. All obtained results are approximated by simple curves of a certain type, which simplifies their use in applied research.
