Description

Expressions are derived for the partial wave expansion coefficients of the scattering matrix elements corresponding to one-particle-exchange Feynman diagrams which are modified by form factors or by Reggeization. A few examples are presented, including the application to nucleon-nucleon scattering in the cloudy bag model. A value of the bag radius Rapprox. =0.8 fm seems to be consistent with the phase-shift analysis in selected partial waves
