- A theoretical program to investigate the role of dislocations in the nucleation of sodium colloids in irradiated rock salt has been outlined. As the first study in the investigation the interaction of radiation-produced defects with the <001> edge dislocation in rock salt, i.e., the edge dislocation in the principal slip system of NaCl, has been considered. The interaction potential between a symmetric defect and the <001> edge dislocation has been determined on the basis of anisotropic elasticity theory. The potential arises from the interaction between the long-range stress field of the dislocation and the displacements around the point defect. The corresponding flow lines, i.e., the lines along which the defects flow to the dislocation, have also been determined. In general, the flow lines are closed loops passing through the center of the dislocation. One of the novel features introduced by anisotropy is the possibility of open flow lines for certain elastic constant values. Along some of these open flow lines defects are attracted to the dislocation, whereas long others defects are repelled from the dislocation of common plane. 33 refs., 17 figs.
