We have searched for the process e+e- → K +K-π0 at energies up to 1.38 GeVin an experiment with the spherical neutral detector at the VEPP-2M e +e- collider. The upper limits of the cross sections for the processes σ(e+e →; φπ: → K +K-π0) < 0.023 nb and σ(e +e- → KK*Yu. M.(892) → K+K -π0) < 0.059 nb have been established at a 95% confidence level. © 2010 Pleiades Publishing, Ltd.
