We present the neutron scattering study of superionic glass (LiI) $_{0.3}$ (LiPO $_{3}$ ) $_{0.7}$ by using the inelastic neutron spectrometer AMATERAS at J-PARC. From the inelastic scattering, low energy excitation or the Boson Peak appears at 6.5 meV. The extra quasielastic scattering was observed in the energy range 1 meV E 3 meV at 285 K but not at 20 K. The Q dependence of the dynamical structure factor S(Q,E) can be approximated to the long-wave acoustic like density fluctuation.
