Abstract
The local transformations of the chemical structure induced in low density polyethylene (LDPE) by irradiation with various ions of different character istics are investigated by using micro-FT-IR system. On irradiation with he avier ions than H+, the remarkable LET effect is found in the transformatio n of the trans-vinylene and the end-vinyl groups. This can not be found on irradiation with H+ or gamma -rays. Moreover, it is suggested that in calcu lation of the stopping power it is important to consider not only the energ y of the injected ion, but also the charge.
