摘要：

The electromagnetic form factors of the neutron in the time-like region have been measured for the first time, from the threshold up to q(2) congruent to 6 GeV(2). The neutron magnetic form factor turns out to be larger than the proton one; the angular distribution suggests that for the neutron, at variance with the proton case, electric and magnetic form factors could be different. Further measurements are also reported, concerning the proton form factors and the <Sigma(Sigma)over bar> production, together with the multihadronic cross section and the J/psi branching ratio into <n(n)over bar>.
