Abstract The detailed shape of the Ps momentum distribution in ice, as given by the 2-photon angular correlation, has been obtained for several temperatures between −40 and 0°C. The narrow component was analyzed in terms of 2 parts, one caused by delocalized and the other by localized Ps. The latter one is interpreted in terms of Ps trapped by thermally excited defects with a formation energy of about 0.4 eV.
