摘要

Ion irradiation of polymers can induce irreversible changes in their macroscopic propcrties.Electronic excitation,ionization,chains scission and cross-links as well as mass losses are acccpted as the fundamental events that givc rise to the observed macroscopic changes.In this work PET films were irradiated with high-
