| Abstract: | We propose a new form of VMD which relates the reactions πN → VN and γN → πN. Our form fits the experimental results within errors. As our restriction is strong enough, we can discuss the kμ2 dependence. Unexpectedly the kμ2 dependence is larger and this suggest the necessity of generalized vector dominance. |
