Relation between the Vertex Function and the Propagators in the Pseudovector Coupling Pion-Nucleon System
Susumu Kinpara
The procedure for deriving the Ward-Takahashi identity is applied to the pseudovector coupling pion-nucleon system in which the isovector and axial-vector current does not conserve…

Effect of the Constant Potential in the Bethe-Salpeter Equation for Proton-Neutron Elastic Scattering
Susumu Kinpara
Nucleon-nucleon potential is given in coordinate space starting from the Bethe-Salpeter equation appropriate to elastic scattering at the intermediate energy region. The next order…
