We report the results of a calculation of the neutrino- and
antineutrino-induced gamma-ray production cross section for oxygen target. Our
analysis is focused on the kinematical region of neutrino energy larger than
~200MeV, in which single-nucleon knockout is known to be the dominant reaction
mechanism. The numerical results have been obtained using a realistic model of
the target spectral function, extensively tested against electron-nucleus
scattering data. We find that at neutrino energy 600 MeV the fraction of
neutral-current interactions leading to emission of gamma-rays of energy larger
than 6 MeV is ~41%, and that the contribution of the p_{3/2} state is
overwhelming.
