N2 - We report the results of a study of high-resolution inelastic electron scattering from O17 and O18 at excitation energies between 15 and 23 MeV. Measurements were performed at 90°for momentum transfers of 1.4, 1.5, 1.7, and 1.9 fm-1 and at 160°for a momentum transfer of 1.7 fm-1. Several prominent narrow peaks were observed in the spectra of both nuclei. The measured form factors for levels in O17 at 15.78, 17.06, 20.14, and 20.70 MeV and in O18 at 18.70, 20.36, and 22.39 MeV are, within experimental uncertainties, completely transverse. These strongly excited states are assumed to arise from isovector M4 transitions of the type 1p3/21d5/2. A simple weak-coupling model is used to assign spins to the levels in O17. Finally, we also report measurements for several narrow states in both nuclei, for which the spins and parities have not yet been identified.
