In proton bombarded GaP a two stage annealing process is observed (stage I near 200° C and stage II near 600° C) and attributed to the annealing of point-like and extended defects, respectively. In neutron irradiated GaP all positron sensitive radiation defects disappear after annealing at 700° C.

In neutronenbestrahltem GaP verschwinden alle positronenempfindlichen Defekte nach Ausheilung bei 700° C.
