Nuclear Instruments and Methods in Physics Research B, 266(12-13), p.3033 - 3036, 2008/06
Times Cited Count:43 Percentile:92.4(Instruments & Instrumentation)Cerium dioxide films are irradiated with high-energy heavy ions with the energy range of 150 MeV to 2.7 GeV, and X-ray diffraction profile is examined. As a result, the data can be explained by creation of nanometer-size ion track with disordered lattice structure, and the ion track is oxygen deficient.
