Abstract
The equation of motion of a dislocation is derived on the basis of the Peierls model. From the equation the mass of a kink is calculated and the interaction between kinks is obtained including the effect of retardation. The mass and the line tension of a vibrating dislocation of infinite length are found to depend on both the frequency and the wave length. It is shown that a resonance scattering takes place for a transverse phonon incident obliquely on a screw dislocation. For a pinned dislocation the use of the concepts of the line tension and the mass is not justified near the pinning points.
