    Abstract

    Aluminium samples in the form of single crystals were treated by uniaxial tensile strain, so that dislocations were practically the sole type of defect produced. A positron lifetime study of these samples, carried out at different dislocation densities, and in a wide temperature range, gives information about the mechanism of positron trapping, including trapping rates, binding energy and the development of defect density with deformation and applied stress.
