摘要

<正> The polyethylene terephalate(PET) film used in this study is a commercial film of about 15μm in thickness and 42% crystallinity. The films were cut to an area of approximately 1.5μ1.0 cm2 and piled up to a stack of thickness slightly larger than the calculated ion projected range. PET stacks were irradiated under vacuum and at room temperature with 1.158 GeV Fe ions delivered by HIRFL to fluences ranging from 5μ1011 to
