Using 15.1^{-1} of data collected by CMD-2 in the Ο-meson energy range,
the branching ratio of the conversion decay ΟβΟ0e+eβ has been
measured for the first time: B(\phi\to\pi^0e^+e^-) = (1.22 \pm 0.34 \pm 0.21)
\cdot 10 ^{-5}.Comment: 13 pages, 6 PostScript figures, uses refmerge.sty. To be published in
