# Abstract:

An evaluation is made of the relative contributions of 2K and 2 pi intermediate states to the isovector part of the nucleons electromagnetic form factor. Dispersion theory is used, and spin and unphysical branch cuts are neglected. It is assumed that the K meson and the nucleon, N, are coupled indirectly through the K-pi and pi-N couplings only. Approximate integrations are carried out for different limiting cases. With the exception of situations where there is not a well-defined trend, all cases show that the 2K-state contribution to the nucleon vector form factor is small. Maximum cross sections and resonance energies for the processes pi pi yields pi pi and pi pi yields KK are also evaluated. Author
