Abstract: (Elsevier)

The cross sections for the reactions e+e−→ϕη , ϕη′ , ρη , ρη′ 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 (ϕη) , 5.3±1.1±0.4 fb (ϕη′) , 3.1±0.5±0.1 fb (ρη) and 3.3±0.6±0.2 fb (ρη′) . The energy dependence of the cross sections is presented using Belle measurements together with those of CLEO and BaBar.
