Abstract : An evaluation is made of the relative contributions of 2K and 2 pi intermediate states to the isovector part of the nucleon's 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 Kpi and piN couplings only. Approximate integrations are carried out for different limiting cases. With the exception of situations where there is not a welldefined trend, all cases show that the 2Kstate 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)
