N2 - The charm semileptonic decays D+→ηe+νe and D+→η′e+νe are studied with a sample of e+e- collision data corresponding to an integrated luminosity of 2.93 fb-1 collected at s=3.773 GeV with the BESIII detector. We measure the branching fractions for D+→ηe+νe to be (10.74±0.81±0.51)×10-4, and for D+→η′e+νe to be (1.91±0.51±0.13)×10-4, where the uncertainties are statistical and systematic, respectively. In addition, we perform a measurement of the form factor in the decay D+→ηe+νe. All the results are consistent with those obtained by the CLEO-c experiment.
