abstract = "The branching fractions of the decays B+→η{\^a} {"}+ν{\^a} {"}and B+→η′{\^a} {"}+ν{\^a} {"}are measured, where {\^a} {"}is either an electron or a muon, using a data sample of 711 fb-1 containing 772×106BB¯ pairs collected at the I (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e-collider. To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q2 range. The resulting branching fractions are B(B+→η{\^a} {"}+ν{\^a} {"})=(2.83±0.55(stat.)±0.34(syst.))×10-5 and B(B+→η′{\^a} {"}+ν{\^a} {"})=(2.79±1.29(stat.)±0.30(syst.))×10-5.",
