Abstract
The presence of a continuum bound state for the nucleon-nucleon (nn) scattering by a nonlocal potential in which Yamaguchi potential enters as an attractive part is examined. It is well-known that an extra node in the radial wave function is directly related to the existence of a continuum bound state in the scattering spectrum. The extra nodes of the wave functions occur in conjunction with the zeros of the Fredholm determinants associated with the physical and regular wave functions of the radial equation for the nonlocal potential. Here we have observed that the extra nodes also occur in conjunction with the zeros of the transition matrix.
