Vacancy-related native defects were studied in semi-insulating GaAs by positron life-time measurements. Both gallium and arsenic vacancies are observed at concentrations of 10{sup 15} - 10{sup 16} cm{sup -3}. The experiments in the dark after illumination manifest the vacancy nature of the metastable state of the EL2 center.
