Positron lifetime measurements in polyethylene under different conditions
Journal de Physique IV : Proceedings
Positron lifetime measurements were performed on polyethylene probes of different densities under various atmspheric conditions within a Y-dose range from 0 kGy up to 1460 kGy. Ve present here experiments non destroying the sample. Four components could be resolved in each lifetime spectrum; the components consist each of a lifetime T and an intensity I. In the dose range investigated the behaviour of the lifetime parameters of the longestlived (74, 14) and the second long-lived (73, 13)doi:10.1051/jp4:1993444 fatcat:hefpqlmozfg2pjacfjd2hvkbra
