Abstract

The trapped positron characteristics are calculated for the carbon-vacancy pair in alpha iron. The method used is based on superimposing free atom electron densities and solving the resulting three-dimensional Schrodinger equation by relaxation techniques. The results are used to interpret positron lifetime measurements in alpha iron doped with controlled amounts of carbon impurities.
