Evaluation of Stopping Powers of Superheavy Ions with $\it{Z}$ up to 124 in Al and U

TL;DR

This study estimates electronic and nuclear stopping powers of superheavy ions with Z up to 124 in aluminum and uranium, comparing different models and experimental data to improve understanding of ion interactions at low energies.

Contribution

It introduces a method to estimate stopping powers of superheavy ions using existing data from lighter ions and compares these estimates with established tables and experimental results.

Findings

Estimated electronic stopping powers align better with experimental data above 0.10 MeV/u.

The approach extends stopping power estimations to superheavy ions beyond existing models.

Comparisons highlight discrepancies and improvements over SRIM data for light ions.

Abstract

Electronic and nuclear stopping powers of superheavy ions with $\it{Z}$ up to 124 and $\it{A}$=300 in Al and U were estimated in the energy range of 0.01-0.20 MeV/u. The corresponding stopping powers were estimated using stopping powers of ions with 6$\leq$$\it{Z}$$\leq$92 obtained from SRIM. The results were compared with those deduced from Northcliffe and Schilling$'$s stopping-power tables and with experimental data for $^{16}$O and $^{19}$F ions in Al. Estimated electronic stopping powers of the light ions agreed better with their experimental values above 0.10 MeV/u than the SRIM data.
