Abstract

Current experimental techniques of two-photon angular correlation in positron-annihilation studies measure the probability distribution of one or two components of the total momentum of the electron-positron pair. We discuss the problem of deducing the probability distribution of the total momentum itself from the experimental data. It is shown that information about two components of the total momentum can in principle determine the probability distribution of the total momentum.
