Abstract
Implantation of helium ions into graphite has been found to produce surface features, which are discussed in terms of radiation damage as a function of depth into the material. Annealing and electron microscope studies show these surface features to be still well defined after annealing at 1500°C. The suggested interpretation is consistent with the large surface stress found in the surface layers of implanted materials.Keywords
