Abstract

Preliminary results of experiment FENICE performed at Adone e + e 2212 storage ring in Frascati are presented here. The J/ψ braching ratios have been determined. At q2 = 4.4GEV2 a new measurement of the proton form factor has been pero≼rmed and at q2 = 4.0 GeV2 a first, preliminary value of the neutron form factor G n =(0.42±0.06) is obtained, assuming |G E | |G M |.
