| Abstract: | Long-range reduction of CuO to Cu2O and Cu was observed by irradiating polycrystals and different planes of CuO single crystals ((110) and (020)) with 16-MeV
nitrogen ions with fluence 1017 cm−2. The infrared absorption spectra show an increase in the number of hole CuO4]5− and electronic CuO4]7− centers. The highest density of electronic centers and reduction occur near the surfaces of the samples.
