The 17,18O(p, n)17,18F reactions were studied at Ep = 35 MeV. Neutron spectra were measured at laboratory angles between 0° and 140°. Results were compared with distorted-wave calculations using the shell-model wave functions. For the 17O(p, n) reaction, cross-section magnitudes as well as the angular-distribution shapes were well described by the calculation. On the other hand, normalization factors of 0.60 were required for the spin-flip excitations observed in the 18O(p, n) reaction leading to the ground (1+), 1.700 MeV (1+) and 2.100 MeV (2-) states. Possible origins of such differences were discussed.
