摘要：

The angular distributions of photon pairs from positrons annihilating in ReO3single crystals were measured along three principal crystallographic directions. The observed curves showed marked structures and anisotropies. A comparison with simple models indicates that main features of these structures and anisotropies can be attributed to the shape of the Fermi surface and the higher momentum components which reflect t2gcharacter of the conduction electrons in this compound. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
