Abstract

<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>

Electromagnetics Properties of Non-Relativistic Deuteron in Ground State

“…The calculated binding energy E is =  2.2427356 MeV [4,6] . From computation, it is known that there is a repulsive force starting from = 0,4 fm, meaning that 0 ≤ ≤ region is an infinite height potential wall, thus the probability to find particles (deuteron) in this interval is zero (see figure 1 and 2) [12] .…”

“…Small differences in this expectation value caused by contribution from charged (virtual) mesons exchange between the proton and the neutron, and this has not been included in Eq. (12) and there is a small admixture of the 1 3 -state in the deuteron ground state [4,10,11] .…”

“…The main contribution is likely to come from the last term, as the 1 3 -component is only a few percent of the total and | | > | | as a result [4,10,11,13] . So that the contribution of quadrupole moment of deuteron can be written as…”

“…Pion may be charged ( + , − ) or neutral ( 0 ), the three form a triplet of isospin, = 1. Pion is member of a group of strongly interacting elementary particles (hadrons) which has medium mass, and are collectively called mesons; pion stands -meson [1][2][3][4] .…”

“…Deuteron has unique property of having an abnormally low binding energy per nucleon, with no excited bound states [4] . In quantum mechanics, the two-particle potential ̂ is displayed as a matrix element between states of the two particle system presented by ket |⃗ ̂1 , 1 The wave function of the deuteron, D can be separated as the product of three parts of the wave function, which are intrinsic wave function of the proton, intrinsic wave functions of the neutron and the orbital wave function that describes the relative motion between the proton and the neutron.…”
