Abstract
Using 3.3 pbâ1 of data collected with the CMD-2 detector in the 720-840 MeV c.m. energy range, the branching fraction of the conversion decay ÏâÏ0e+eâ has been measured: B(ÏâÏ0e+eâ)=(8.19±0.71±0.62)Ã10â4. The upper limits for the branching fractions of the following conversion decays have been obtained at the 90% confidence level: B(ÏâÏ0e+eâ)<1.6Ã10â5, B(Ïâηe+eâ)<0.7Ã10â5 and B(Ïâηe+eâ)<1.1Ã10â5.
