Abstract Li salts of acrylic acid were grafted to polyethylene, PE. It is known that li is mobile in this material at room temperature, and hence can act as a probe for newly introduced defects. After irradiation of PE(Li) with 100 keV He+ ions at different fluences the Li depth distributions were measured by NDP. Changes in the Li distributions are observed which are ascribed to bonding at oxygen, the latter one preferentially penetrating into the PE via the irradiation-damaged sample surface. With increasing sample age, i.e. after exposure to ambient atmosphere for more than half a year, Li appears to lose its original mobility.
