<span>The interaction of two nucleons in the form of protons and neutrons as a bound system in the local <span>potential, known as the deuteron, has been investigated. Two-nucleon interaction potential field <span>through the core will produce a nuclear force where the force between nucleons is generated by the <span>exchange of mesons. One of the members of the group of meson particles is pion. Pion can be <span>charged<span><span><em>π </em><span>+ <span><em>,</em><span><em>π </em><span>-<span><span>or neutral,<span><span><em>π </em><span>0<span><span>. Interaction potential form of the simplest is the exchange of one <span>pion potential (OPEP), <span><em>V </em><span>OPEP <span>, which has a radially independent of Yukawa potential. <span>In this study, the first step taken is to perform discretization of the OPEP potential expression <span>coupled with the equation of the boundary conditions due to the influence of interaction distances. <span>The next step is to implement a programming technique to obtain the value associated with the <span>potential influence of OPEP in the deuteron, the magnitudes of the static deuteron, such as a pion <span>distance exchange, and mass estimates pion involved in this interaction.</span></span></span></span></span></span></span></span></span></span><br /></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>

The two-nucleon interaction, via the exchange of scalar mesons, is examined in a nonperturbative manner. 'Schrödinger' equations are derived, and nonlocal potentials arise naturally. Both scattering and bound states are examined. A half-off-shell T matrix is obtained, and corresponding phase shifts are evaluated. In the bound state, a variational calculation is employed to determine the coupling constant.

The nucleon–nucleon interaction potential in hot/dense nuclear matter is studied within the QHD-I model. We find that a Yukawa potential, which contains attractive and repulsive terms, acting between nucleons is modified by the variation of the Debye mass. In particular, a nucleon system described by this Yukawa potential will be unbound at some critical T and μ. The critical point is very close to that of the L-G phase transition given in the literatures.
