Evaluation of the stopping powers of superheavy ions with values of Z up to 124 in Al and U

Abstract

The electronic and the nuclear stopping powers of superheavy ions with values of Z up to 124 and A = 300 in Al and U were estimated in the energy range of 0.01–0.20 MeV/u. The corresponding stopping powers were estimated by using the stopping powers of ions with 6 ≤ Z ≤ 92 obtained from SRIM. The results were compared with those deduced from Northcliffe and Schilling’s stoppingpower tables and with experimental data for 16O and 19F ions in Al. The estimated electronic stopping powers of the light ions agreed better with their experimental values at energies above 0.10 MeV/u than the SRIM data did.
