摘要The N-*(1535) resonance contributions to the pn -> d phi reaction are evaluated in an effective Lagrangian model. The pi-, eta-, and rho-meson exchange are considered. It is shown that the contributions from pi- and rho-meson exchange are dominant, while the contribution from eta-meson exchange is negligibly small. Our theoretical results reproduce the experimental data of both total cross section and angular distribution well. This is more evidence that the N-*(1535) resonance has a large ss component leading to a large coupling to N phi, which may be the real origin of the Okubo-Zweig-Iizuka rule violation in the pi N and pN reactions.
