Description

Results are presented for the total cross section of e+e- annihilation into two hadrons at 1.6 GeV: sigmasub(ππ)=sigmasub(KK)=(1.8+-1.1)x10-33 cm2. From these values are obtained the time-like electromagnetic form factors of these mesons: (mod Fsub(π))2=0.24+-0.14 and (mod Fsub(K)))2=0.46+-0.26. (Auth.)
