Abstract The authors have studied a total of 26208 events produced in (e/sup + /e/sup -/) reactions in the energy range from 1.2 to 3.0 GeV. All these events had to have at least two charged particles in the final state with an energy cut-off, depending on the nature of the particle: E/sub e/>or=100 MeV; E/sub pi />or=100 MeV; E/sub K/>or=225 MeV. The above conditions were imposed by the fast electronic trigger. The events were of the following nature: e/sup +/e/sup -/ to e/sup +/e/sup -/ (collinear, coplanar), e/sup +/e/sup -/ to e/sup +/e/sup -/ (acoplanar- mod phi mod >or=5 degrees ), e/sup +/e/sup -/ to mu /sup + / mu /sup -/ (collinear, coplanar), e/sup +/e/sup -/ to mu /sup +/ mu /sup -/(acoplanar- mod phi mod >or=5 degrees ), e/sup +/e/sup -/ to h /sup +/h (collinear, coplanar) and e/sup +/e/sup -/ to h/sup +/h/sup - /+anything.
