Abstract

Since channeled ions are scattered by any atoms which are displaced from lattice sites, channeling measurements can be used to study a variety of lattice defects. Three areas of investigation will be described: (1) dechanneling caused by multiple scattering from point defects, dislocations, thermal displacements, and disordered regions; (2) direct backscattering from amorphous zones; and (3) direct backscattering from displaced solute atoms. In topic (3) the following point defect-solute atom configurations have been identified: (a) 〈100〉 mixed dumbbells in fcc metals, in which a small solute atom and a host atom straddle a lattice site; and (b) vacancy complexes in fcc metals, in which 3, 4 or 6 vacancies surround a large solute atom which is at a position ( 1 6 , 1 6 , 1 6 )a 0, ( 1 4 , 1 4 , 1 4 )a 0 or ( 1 2 , 1 2 , 1 2 )a 0 , respectively.
