The cross sections for the reactions e+ e- → φ{symbol} η, φ{symbol} η′, ρη, ρ η′ have been measured using a data sample of 516 fb- 1 collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. The corresponding values of the cross sections are: 1.4 ± 0.4 ± 0.1 fb (φ{symbol} η), 5.3 ± 1.1 ± 0.4 fb (φ{symbol} η′), 3.1 ± 0.5 ± 0.1 fb (ρ η) and 3.3 ± 0.6 ± 0.2 fb (ρ η′). The energy dependence of the cross sections is presented using Belle measurements together with those of CLEO and BaBar. © 2009 Elsevier B.V.
