Cottrell and Jaswon gave the detailed theory of the distribution of solute atoms which interact weakly with a slowly gliding dislocation. Without giving complete solutions, it was shown how the analysis could be modified to treat a climbing dislocation. As already indicated by Takeuchi and Argon, the results were similar for glide and for climb. Attention was also drawn to the case in which the interaction between the dislocation and a solute atom was large in comparison with thermal energies, and the solute atmosphere approximates a line odilatation-free stress field of this line of dilatation interacts with solute atoms which produce uniaxial strains.
