摘要：

It is shown that in the impulse approximation the ratio of the near-threshold np --> {np}(I=0) eta to np --> d eta production rates depends weakly upon the form of the production operator and can be estimated using low-energy neutron-proton dynamics. The agreement between the predictions and the preliminary results of a recent measurement suggests that any strong eta final-state interaction must largely cancel in the production ratio.
