Abstract
Two-dimensional angular correlations of positron-annihilation radiation in Li and K have been measured with high angular resolution. The results are compared with two-photon momentum densities calculated by the Korringa-Kohn-Rostoker method. The comparison shows good agreement for the (110) and (200) higher-momentum components and thus implies that many-body enhancement effects are comparable with those in the (000) zone.Keywords
