摘要：

Recent progress on the scattering of an ortho-positronium beam is reviewed. Similarities are noted amongst the total cross-sections for positronium scattering from various targets. The integrated Ps fragmentation cross-sections, determined by detecting each of the ejected particles, are presented for collisions with He and Xe atoms. In the case of He, a good agreement is found with theory, whilst preliminary results for Xe suggests that significant target ionisation occurs for this target at 30 eV Ps impact energy.
