Abstract

At room temperature， polyethylene terephthalate(PET) foil stacks were irradiated by 25 MeV/u Kr ions in the electronic stopping power range(3.3--7.66 keV/nm) and the fluence range from 5×10¹¹ to 3×10¹² ions/cm². The behaviour of the main function groups with fluence and electronic stopping power were studied by using Fouriertransforminfrared(FTIR) spectroscopy， the degradation of the function group was investigated with the Lorentz fitting subtracted baseline. The amorphous processes in the latent tracks of PET were studied by Xray diffraction(XRD) measurements. The Kr ion induced degradation crosssection and amorphisation crosssections(radii) for different electronic energy loss were acquired from the experimental data(FTIR and XRD) by exponential decay function respectively. 
