Dose dependence of generation and annealing of point defects induced by the bombardment of Al(111) single-crystal surface by Ar$^{+}$ ions with energy of 600 eV in extra-high vacuum is studied in detail using the method of low-energy electron diffraction. Possibility of analysis of changes in intensity of diffraction reflexes of slow electrons directly during ion bombardment that excludes annealing effect at subsequent holding at room temperature is shown. Based on analysis of diffraction reflexes, values of activation energy of point defects are obtained.

Key words: point defects, surface, single-crystal, ion bombardment, low-energy electron diffraction.
