摘要：

The electric-field-gradient asymmetry parameter has been measured in several vitreous chalcogenides at arsenic sites which undergo a strong quadrupolar coupling. Results in vitreous As2S3 and As2Se3 reveal a cylindrical local symmetry which contrasts with the distortion associated with the lamellar structure crystalline As2S3. However, in amorphous As25Te75 and As45Te55 the local environment of arsenic displays a sizable distortion. © 1979 The American Physical Society.
