As the In concentration Fhl x Snx Te(In) is raised above CIn ~2 at.%, the lifetime of the nonequilibrium electrons is observed to decrease sharply, as does the critical field for photoconductivity quenching. The kinetics of the photoconductivity at Cln £ 2 at. % and T< 20 К suggests a correlated change in the structure of impurity centers.
