Low-energy ({ital E}{sub 0}=15{endash}40 eV), high-energy-resolution, electron-energy-loss spectra of nitric oxide (NO) have been measured and spectrally deconvolved. This process yielded direct absolute differential cross sections (DCS) for electron-impact excitation of the electronic states of the NO molecule. Integration of these DCS gives integral cross sections (ICS), which confirm earlier estimates that the magnitudes of the NO ICS are one to two orders smaller than the analogous transitions in N{sub 2} and O{sub 2}. In this paper we present clear evidence for the observation of the {ital L}{prime}{sup 2}{Phi} electronic state, showing a {sup 2}{Pi}{sub {ital r}}{r_arrow}{sup 2}{Phi} excitation transition in an electron-scattering experiment. {copyright} {ital 1996 The American Physical Society.}
