摘要：
Some analyses of the electromagnetic form factors of the nucleon and some analyses of the nucleon-nucleon potential favor a large coupling of the phi meson to nucleons. This is frequently quoted by advocates of a large s (s) over bar component of the nucleon. It is shown that such large OZI-violating couplings are incompatible with data on 0 production in backward direction via nucleon exchange.
