Abstract

The thermal conductivity has been measured over the temperature range 0.06 6 K for a LiF crystal before and after deformation by compression in which all possible dislocation-slip planes were activated, and after reduction in sample size and, finally, following -ray irradiation. At temperatures below 1 K the results are in agreement with a model of phonon scattering by fluttering dislocations. At T1 K the data suggest that dislocation dipoles may dominate the scattering of phonons.
