Investigation of nucleon-nucleon interaction with confined one gluon exchange potential and one pion exchange potential

The Nucleon-Nucleon (N-N) interaction in the singlet (¹S₀) and triplet (³S₁) channels have been studied in the framework of Relativistic Harmonic Model (RHM) using the Resonating Group Method (RGM) in Born-Oppenheimer approximation. The full Hamiltonian consists of the kinetic energy, two body confinement potential, confined one gluon exchange potential (COGEP) and one pion exchange potential (OPEP). Contribution of COGEP and OPEP to the adiabatic N-N interaction potential is discussed. The presence of short range repulsion for the N-N interaction is also investigated and the reason for the same has been attributed to the presence of color magnetic terms in the COGEP. (author)
