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

摘要

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 superheavy 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.
