Abstract
The critical breakaway stress has been measured for basal edge dislocations in zinc with strongly pinned ends and initial lengths which varied from 50 to 250 μm. A line energy of 4.5 eV/atom distance is deduced from these measurements for a screw-orientated dislocation which is parallel to, and approximately 2 μm below, a free surface. Core energy parameters are calculated from a knowledge of the total energy and the energy in the linear elastic strain field.
