Abstract

A three-body version of the CTMC method was applied to interpret the experimental data obtained y Armitage et al. for the fragmentation of the Ps in collisions with He atoms. Thus, the calculations were carried out for collisions energies 13, 18, 25, and 33 eV. The model significantly overestimates the total break-up cross sections. At the same time, it correctly reproduces the peak observed in the experimental longitudinal energy distribution of the emitted positrons at Eres/2, supporting the idea of a peak formation mechanism similar to electron loss to the continuum (ELC) in atomic collisions.
