Determination of the electron momentum distribution of matter by the positron-annihilation method

  • Published:
Soviet Physics Journal Aims and scope

Abstract

A method is developed for recovering the density function of annihilating electron-positron pairs from the angular correlations of the annihilation gamma rays. On the basis of this positron-annihilation mechanism, the electron density functions of the matter are determined from the time spectra of the positron lifetime and the angular distributions of the annihilation gamma rays.
