Abstract
Angular correlation spectra of positron annihilation in Y-zeolite adsorbed
with bases (ammonia, water, and alcohol) were studied. Results by the techn
ique successfully reveal that there exist two types of Bronsted acid sites
with different acidic strengths which require temperature of desorption of
the base at about 200 and 400(degrees)C.
