Abstract
Specific heat and Raman scattering were measured on sintered samples with x around 0.5, which show a sharp metal-to-insulator transition (MIT) with increasing temperature. Specific heat below MIT can be well expressed by C = γT + βT3 + δT3 ln T with parameters comparable to those of TiBe2. Spectrum of Raman scattering shows no anomaly through MIT.
