Measurements have been made of the cross section factors for cascades in N14(p,?) through the 6.79, 6.16 and 5.18 MeV states of O15, and for the ground-state transition, over the proton energy range from 210 to 1070 keV. Individual extrapolations to stellar energy are made. For the sum of the cross section factors, the zero-energy intercept is S(0) = 2.75±0.50 keV · b with zero slope. Over most of the energy range, the cascades through the 6.79 and 6.16 MeV levels dominate. At stellar energies, these account for 50% and 40%, respectively, of the reaction rate. The extrapolation is in satisfactory agreement with the results of other workers at low energies.
