Abstract
The modifications of optical absorption spectra and of hardness induce d by irradiations with various ion species in three polymers have been determined quantitatively by means of spectroscopic ellipsometry and of nanoindentation tests. Their analysis in terms of amounts of energy deposited respectively in nuclear collisions and in electronic excita tions indicates that the latter have a predominant effect on both prop erties. The efficiency of ionizations depends on the ability of radica ls formed under each ion impact to interact.
