dc.description.abstract | In t.his t.hesis, we work out. t.he low-energy (~300Me V) form of t.he protonproton (p-p), neutron-neutron (n-n), and proton-neutron (p-n) int.eraction potentials taking the field-theoretic view that these interactions are mediated through the exchange of 7r 0 , 7r± mesons. In this process we reproduce the exact form of Yukawa potential. vVe extend these calculations to obtain an approximate form of two-pion exchange potential. vVe then generalize t.he formalism to include isospin and arrive at the correct form of the low-energy nucleon-nucleon (N-N) potential. In the process we establish the charge independent hypothesis of nuclear forces. Further we observe that our model for the long-range part of N-N forces correctly predicts that for I = 0, the two nucleon system exists as a bound state (deuteron nucleus) while for I = 1, it exists as scattering states | en_US |
