Estimation of the Stopping Powers of the ^AZ = ^(300)120 Ion in Al and UO_2

The electronic and nuclear stopping powers of a superheavy ion with Z = 120 and A = 300 in Al and UO_2 were estimated in the energy range of 0.01-0.20 MeV/u. The electronic and nuclear stopping powers of ions with 6 ≤ Z ≤ 92 obtained from Stopping and Range of Ions in Matter (SRIM) were used to estimate the corresponding stopping powers of the super-heavy ions. The results were compared with those deduced from Northcliffe and Schilling's stopping-power tables. In the lower energy region the contribution of the nuclear stopping powers is significant in both media, while it is not negligible even in the higher energy region.
