Abstract
The expression for the angular correlation of two-photon annihilation radiation for positrons colliding with molecular hydrogen is derived. The one-state approximation is used, and a one-centre expansion of the hydrogen wave function is assumed. Results obtained using a simple H2 wave function yield a half-width of the angular distribution which is in agreement with the observed results for positrons annihilating in liquid hydrogen. Comparison is made with corresponding results for the annihilation rate.
