The electrical resistivity of pure yttrium single crystals (rho/sub 273.2//rho/sub 4.2/approx. =700) oriented along the <0001> and <1010> axes has been investigated in the temperature range 4.2--300 K. It was established that the scattering of electrons by phonons is described by the Bloch--Grueneisen function for both orientations over the whole temperature range, with the parameter THETA/sub R/ equal to the Debye temperature THETA/sub D/. It was found that a contribution to rho(T) quadratic in the temperature is two orders of magnitude greater than in other transition metals. It is shown that the anisotropy in the electrical resistivity of yttrium at Tapprox.THETA/sub D/ is completely determined by the anisotropy of its Fermi surface.
