摘要：

About 300 000 e(+)e(- -->) phi --> (KLKS0)-K-0 events in the center of mass energy range from 984 to 1040 MeV were used for the measurement of the phi meson parameters. The following results have been obtained: sigma(0) = (1367 +/- 15 +/- 21) nb, m(phi) = (1019.504 +/- 0.011 +/- 0.033) MeV/c(2), Gamma(sigma) = (4.477 +/- 0.036 +/- 0.022) MeV, Gamma(e+e-) . B(phi --> (KLKS0)-K-0) = (4.364 +/- 0.048 +/- 0.065) . 10(-4) MeV. (C) 1999 Elsevier Science B.V. All rights reserved.
