Description
Summary:The maximum etchable ranges of heavy ions such as 128U (16.53 MeV/u), 208Pb (13.6 MeV/u), 197Au (11.4 MeV/u), 132Xe (14.5 MeV/u, 13.02 MeV/u and 5.6 MeV/u) and 93Nb (18.0 MeV/u) in CR-39 and 238U (16.53 MeV/u, 15.0 MeV/u and 5.6 MeV/u), 198Au (13.42 MeV/u) and 132Xe (14.5 MeV/u and 5.6 MeV/u) in Lexan have been determined experimentally. The ranges of these heavy ions in these detectors have also been computed theoretically using the Mukherjee and Nayak stopping power equations. A reasonably good agreement has been observed between the experimental and theoretically computed values. Finally, a theoretical study of the relation R(range) = aE b (energy) has been made using the Mukherjee and Nayak stopping power equations for different heavy ions in CR-39 and Lexan polycarbonate.
