Abstract
Damage in polycarbonate (PC) irradiated with B+, C+, Si+, Cu+, and Au+ ions at energies between 0.19 and 2.4 MeV was studied using a variable-energy positron beam by measuring the Doppler broadening of positron annihilation γ-rays as a function of incident positron energy. Positron data were plotted, instead of incident positron energy E, as a function of average positron implantation depth normalized to average ion implantation depth. Such plots enable damage distributions produced by ions with different implantation ranges to be compared directly. We found that normalized damage distributions in ion-irradiated PC vary systematically with dimensionless reduced energy proposed by Lindhard et al. (K. Dan. Vidensk. Selsk. Mat.-Fys. Medd. 36 (1968) 10)
