High energy ion irradiation effects on polymer materials. LET dependence of G value of scission of polymethylmethacrylate (PMMA)

Abstract

Linear energy transfer (LET) dependence on the probability of main chain scission of polymethylmethacrylate (PMMA) was investigated. The probability was obtained from decreases in molecular weight measured by the gel permeation chromatography (GPC), and LET was evaluated by TRIM code. The scission probability as a function of LET was almost constant in the low LET, and decreased in the high LET ion irradiation. The mechanism was interpreted from the model of spur-overlapping along an ion`s path. (author)
