Abstract
The properties of Ps-like systems in atactic and isotactic polypropylene were investigated by lifetime measurements and by magnetic quenching experiments. The magnetic quenching results are markedly different: in atactic polypropylene they indicate the formation of an electron-positron bound system, 'swollen' in comparison with a Ps atom in free space. The magnetic quenching for isotactic polypropylene is anomalously high at low fields and seems to suggest the existence of two Ps-like centres, related to regions with different degrees of crystallinity.
