| In earlier measurements of momentum distribution of annihilating e+e- pairs the intensity of o-Ps component seemed to be much higher than that expected from the lifetime data. In this paper we show that such a deviation disappears if one assumes that the pick-off component of angular correlation of annihilation radiation is narrower by 10% than the component related to free annihilation. |
