Low-energy state of np system in the Gaussian potential

The Gauss potential parameters of np-interaction in triplet and singlet states using nowadays meanings of low-energy scattering characteristics are specified. The calculations have been performed by the finite difference method which permits to determine comparatively quickly and with high precision not only energy and wave functions of bound states but also state functions with positive energy. By means of thus obtained potentials the calculations of some characteristics of np-interaction have been performed using variational method with wave function decomposition over the non orthogonal basis
