Results are given of measurements of the thermal conductivity of single-crystal specimens of solid hydrogen with ortho-modification content from 0.21 to 4.4% in the temperature range 1.4–11° K. An effect was found ofclustering of the ortho-molecules on the thermal conductivity. The relaxation time of the ortho-subsystem was determined in the temperature range 1.5–3° K. It follows from the results obtained the thermal resistivity of the crystals, associated with that scattering of phonons by the ortho-subsystem with random distribution of ortho-molecules in the lattice up to 0.21% o–H2, is proportional to x2T−3.
