| Abstract: | By means of the Cloudy Bag Model (CBM), the contributions of pion field to nucleon-nucleon potential are calculated. It is shown that the results given by CBM are in good agreement with One-Pion-Exchange-Potential (OPEP) at large distance. Futhermore, in order to take into account the contributions of vector meson to nuclear force, we extend the CBM to include the vector meson and quark-antiquark-vector meson interaction. Using the Extended Cloudy Bag Model (ECBM) and Breit-Fermi equation of two nucleon system, through Foldy-Wouthuysen transformation, we get the nucleon-nucleon interaction which is in good agreement with naive One-Vector-Meson-Exchange-Potential (OVEP) in nonrelativistic limit, but effects of nucleon structure to nuclear force (form factor) are given. |
