In the extended U(3) × U(3) NJL quark model, semileptonic decays of ρ, ω, ϕ, η and η′ mesons in both the ground and first radially excited states are described. Quark loops of the anomalous type are considered, which are based on the vertex η→ VV. The obtained results are in satisfactory agreement with the existing experimental data. In addition, a number of predictions for experimentally unmeasured decays of radially excited mesons are presented.
