Abstract
It is demonstrated that N(pi, e(+) e(-))N measurements will provide ne w information about the nucleon timelike form factor in the phi meson region including the value of the phi N coupling g(phi NN) Using vecto r meson dominance, N(pi, e(+) e(-))N calculations reveal a 3 order of magnitude enhancement from the phi resonance coupled to the nucleon co mpared to the expected background phi production from the rho pi phi c ontribution through rho exchange. The effect from phi N coupling in th e nucleon form factors yields a novel experimental signature for OZI ( Okubo-Zweig-Iizuka) violation and the related strangeness content of t he nucleon.
