摘要：

The disordering in the fused lithium metatitanate (Li2TiO3) irradiated with high energy ions (160 MeV Xe, 80 MeV O) was examined by room-temperature X-ray diffraction and Raman spectroscopy. The exposure of Li2TiO3 to Xe ions at fluences of 3.3 x 10(16) and 3.4 x 10(18)/m(2) was found to cause complete disordering in its surface layer, unlike the surface layer exposed to O ions up to maximum fluence of 1.4 x 10(20)/m(2). An extent of disordering with irradiation is associated with the electronic stopping power of the incident ions in Li2TiO3 rather than the fluence and accumulated radiation dose.
