On the basis of researches of electrical conductivity and plasma reflection of crystal of Bi\\.bSbQ.z,Tez the regularities of temperature reaction of static and optical times of relaxation in the range from 85 to 300 К were received. It was found, that temperature dependence of static time of relaxation in the range of 85-150 К corresponds to dispersion degenerate, and in the range of 200 300 К nondegenerate carriers of charge on acoustic fluctuations of lattice. The divergence of values of static and optical times of relaxation correlating with rapprochement of energy of plasmons and transitions of carriers between nonequivalent extremum of valence zone is revealed.
