In this paper we address the question of whether Rutherford backscattering (RBS) can be applied to the study of polymers in such a way that experimental results will provide accurate information on the depth composition of the polymer. Our scanned-beam RBS results suggest that, for room temperature analysis of polyethylene terephthalate (PET), there is a fluence limit below which beam induced compositional changes can be neglected. Cooling to the sample of LN2 temperature during RBS analysis causes the oxygen to carbon concentration ratio to remain unchanged, apparently because no significant outdiffusion of beam generated gas molecules can occur at LN2 temperature.
