The radiation damage process was directly observed by means of field ion microscopy and was compared with computer simulation results. Specimens were bombarded with 300keV Ni+ ions to doses which ranged from 1.4 x 1016 to 1.4 x 1019/m2. The size distribution and the morphology of the irradiation defects was deduced from the field ion microscopic observations.
