Abstrakt:	A technique for determining the sizes of vacancies and pores in metals by positron annihilation spectroscopy (PAS) in the angstrom and nanometer ranges is proposed. Following the proposed technique, the radii of vacancy-type defects in iron are estimated. The obtained results are of special interest for research programs in which properties of critical engineering materials [49-55] are studied using beams of slow positrons at positron facilities (see Research Program at the LEPTA Facility, I. Meshkov for LEPTA collaboration). [ABSTRACT FROM AUTHOR]
