    Research output: Contribution to journalJournal articleResearchpeer-review


    Aluminium single crystal samples were treated by uniaxial tensile strain. Positron lifetime studies carried out at different dislocation densities and in a wide temperature range give information about the mechanism of positron trapping, as well as trapping rates, binding energy and the development of defect density with deformation and applied stress.
