Abstract
Dislocation loops are observed in sodium chloride crystals heavily doped with barium chloride. The behaviour of the loops under the action of mechanical stresses generated when cooling the crystal is consistent with their being negative prismatic, with a Burgers vector parallel to [110]. Their origin appears to be from the operation of Bardeen–Herring sources. The relationship of this work to that of other authors is discussed.Keywords
