Abstract
Vibrational spectra of VO{sub x} solid solutions have been measured by neutron spectroscopy method at various concentrations of oxygen (x=0.03; 0.06; 0.11). For VO{sub 0.06} the vibrational spectra is presented for quenched alloy and after annealing at 200 deg C and 320 deg C. With increasing of oxygen concentration the average frequency of vanadium atoms spectra is increased. The similar effect have been established for VO{sub 0.06} alloy after annealing. The frequency of oxygen atom - {omega}{sub 3}, with polarization vector along tetragonality axis is decreased from 91 MeV in VO{sub 0.03} to 84 MeV in VO{sub 0.11}. The impurity band widths are noticeably decreased ({approx} 30%) during transition to ordered phases. 7 refs.; 3 tabs.; 8 figs.
