Abstract

A semiquantitative calculation of the cross sections for interaction of vacancions in solid He4 with different lattice defects is performed. Estimates are obtained for the coefficient of diffusion of vacancions. A macroscopic equation describing the kinetics of vacancions, including the possibility of their creation and absorption, is formulated. The contribution of vacancions to thermal conductivity is calculated.
