ON THE RELATIVISTIC FIELD-THEORY MODEL OF THE DEUTERON II

The relativistic field theory model of the deuteron suggested previous ly is revised and applied to the calculation of the cross sections of the low-energy radiative neutron-proton capture n + p --> D + gamma an d the low-energy two-proton fusion p + p --> D + e(+) + nu(e). For the low-energy radiative neutron-proton capture n + p --> D + gamma our r esult agrees well with both experimental data and the potential model prediction. In the case of the two-proton fusion the cross section obt ained is 2.9 times as much as that given by the potential approach. Th e obtained result is discussed in connection with the solar neutrino p roblem. (C) 1997 Elsevier Science B.V.
