摘要: Abstract Electron-positron momentum densities are calculated for the (001–110) plane in Ge at normal and increased pressure. The calculations based on independent particule approximation coupled with pseudopotential method. shapes of profiles indicate that angular correlation positron annihilation radiation (ACPAR) along different crystallographic directions highly sensitive to
