    • Abstract

       

      The two photon pair momentum density and the angular correlation curves for positron annihilation radiation from copper have been obtained by a band structure calculation, employing Hubbard’s approximation scheme. A comparison of the calculated curve for the long slit geometry with the experimental results shows that the theory rather overestimates the contributions in the high momentum region. An angular correlation curve for a point slit geometry is also calculated.
