N2 - The distribution of the local transformations induced in a low density polyethylene irradiated with various ion-beams was observed by using micro-FT-IR system. The predominant transformations induced by irradiation are crosslinking, trans-vinylene, end-vinyl and vinylidine. The depth profile of the trans-vinylene resembles the Bragg curve, but that each of the end-vinyl and the vinylidine shows rather complicated profile. The irradiation effect of H+ ions is similar to that of γ-rays, but on irradiation with the ions heavier than H+, the species induced are found to depend on the beam fluence and the stopping power of the ion.
