Abstracts

EN

The influence of the electron-positron interactions on the momentum density of annihilation quanta in real metals is discussed. The role of momentum dependence of two-particle electron-positron correlations is set forth. The effective densities describing electron-positron correlations are presented for valence electrons in simple metals.
