Popis:	About 300 000 e + e − → φ → K 0 L K 0 S events in the center of mass energy range from 984 to 1040 MeV were used for the measurement of the φ meson parameters. The following results have been obtained: σ 0 =(1367±15±21) nb, m φ =(1019.504±0.011±0.033) MeV/c 2 , Γ φ =(4.477±0.036±0.022) MeV, Γ e + e − · B ( φ → K 0 L K 0 S )=(4.364±0.048±0.065)·10 −4 MeV.
