摘要：
The sensitivity of polarization observables in the reaction NN-->NN phi slightly above the threshold is studied with respect to the details of the one-boson exchange model and a possible admixture of hidden strangeness in the nucleon. It is shown that the finite-energy predictions differ strongly from the threshold predictions. A measurement of the beam-target asymmetry and the phi decay anisotropy can help to disentangle the role of various reaction mechanisms. [S0556-2813(99)07302-1].
