Annotation This work presents research in the study of copper nanotubes (Cu-NTs) electrochemically deposited in pores of PET track-etched membranes and irradiated with accelerated C+3 ions with energy of 1.75 MeV/ nucleon; the fluence of accelerated ions was varied in the range from 1  109 to 5  1011 ion/cm2. The morphology and chemical composition of the un-irradiated samples were elucidated using scanning electron microscopy and energy dispersive analysis. An investigation of crystal structure defects that occur during irradiation of Cu-NTs was carried out by X-ray diffraction technique. XRD patterns of Cu-NT after irradiation with high fluence of C3+ ions show the appearance of the characteristic peaks of the polymorphic modification of carbon with a hexagonal structure related to three-layer rhombohedral -graphite with the R3m (160) space group (PDF 47-1154). The most intense peaks are related to (0015) and (104) Miller indices. The absence on the spectra of peaks characteristic for Cu2C and CuC2 copper carbide compounds indicates that the carbon present in the Cu-NT structure as a solid substitutional solution. The changes in such parameters as the size of crystallites, deformation and stress of the crystal lattice of copper NTs etc. are discussed.
