An investigation was made of the temperature dependences of the thermoelectric power (in the 300--1050/sup 0/K range) of yttrium, gadolinium, and terbium single crystals parallel and perpendicular to the hexagonal axis. The results led to a hypothesis that a reduction in the mean free path could be responsible for an increase in the indeterminacy of the carrier quasimomentum and ''smearing'' of the Fermi surface resulting in a nonmonotonic variation of the thermoelectric power at high temperatures.
