China's Nuclear Force Modernization

We propose a new approach of the Brueckner-AMD that makes the antisymmetrized molecular dynamics (AMD) calculations possible with realistic nuclear forces. In this method, we solve the Bethe-Goldstone equation and calculate the G-matrix for every nucleon pair described by wave packets of AMD correctly. We report the results of applications to light nuclei with the Brueckner-AMD.

Charge Dependence

Deuteron breakup reactions are basic laboratories for testing nuclear force models. Recent improvements in the data analysis allow for direct identification of neutrons in the BINA detection setup. This opens up the opportunity to study new aspects of few-nucleon system dynamics like charge dependence of nuclear force or Coulomb interaction. In this paper we determine regions along the kinematical curves where differential cross section of deuteron-proton breakup reactions can be measured by the proton-neutron and proton-proton coincidences simultaneously. %In this paper we determine regions along the kinematical curves where differential cross section of $^1$H$(d,pp)n$ and $^1$H$(d,pn)p$ breakup reactions overlap. This is particularly useful for validation of the neutron detection technique.

Upper Limit

As known the Weak Nuclear Force or Weak Interaction(WI) acts between quarks (Qs) and leptons. The action of the WI is mediated by highly massive gauge bosons. How does a nuclear Q emit such a massive particle, approximately 16000 or 40000 times its mass? Who provides so much energy to a up Q or a down Q? However, it must be considered that according to Quantum Mechanics it is possible to loan temporarily some energy, but to a precise and binding condition, established by the Uncertainty Principle: the higher the energy borrowed, the shorter the duration of the loan. Our calculations show that the maximum distance these bosons can travel, i.e. the upper limit of their range, corresponds to 1.543×10-15 [cm] for particles W+ and W- and 1.36×10-15[cm] for Z° particles.

Potential Form

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