“…For protons in isobutane we could find experimental data only in the energy range below 1 MeV/nucleon [23]. The agreement is within [24][25][26][27][28][29][30], CF 4 [22], Al and mylar [31][32][33][34][35][36] with the results of SRIM-2008 calculations (red solid line). The blue dashed lines show the SRIM-2008 stopping powers normalized to the experimental data.…”

“…For this reason theoretical calculations are usually compared to experimental measurements involving a molecular hydrogen target. Measurements of the stopping cross section for protons passing through a H 2 gas, which cover the range from 10 keV to 2 MeV, have been performed by Reynolds et al [5], Reiter et al [6], and Golser and Semrad [7].…”

The stopping cross section for protons passing through hydrogen is calculated for the energy range between 10 keV and 3 MeV. Both the positive and neutral charge-states of the projectile are accounted for. The two-centre convergent close-coupling method is used to model proton collisions with hydrogen. In this approach electron-capture channels are explicitly included by expanding the scattering wave function in a basis of both target and projectile pseudostates. Hydrogen collisions with hydrogen are modelled using two methods: the single-centre convergent close-coupling approach is used for the calculation of one-electron processes, while two-electron processes are calculated using the Born approximation. The aforementioned approaches are also applied to the calculation of the charge-state fractions. These are then used to combine the proton-hydrogen and hydrogen-hydrogen stopping cross sections to yield the total stopping cross section for protons passing through hydrogen.

Energy deposition of heavy ions when penetrating a material is of crucial importance in determining the damage to materials with implications in areas such as material science, plasma physics, radiotherapy and dosimetry. Due to the N-body electron problem, it has been thought that the electronic stopping cross section is unique for a given projectile-target combination and differs from system to system. In this work, we show that within the Bethe theory, there is a universal scaling when the electronic stopping cross sections and projectile kinetic energy are scaled properly in terms of the target mean excitation energy, I 0 , for all projectile-target combinations. We show that the scaling is given by I 0 S e /π e 4 Z * p as a function of m e E p /M p I 0 , thus showing the importance of the characterization of the mean excitation energy. The scaling law expresses a systematic and universal behavior among complex projectile-target systems in the energy deposition, characterized by the minimum momentum transfer during the slowing down process. We provide an analytic expression for the universal scaling law for the stopping cross section of any projectile-target combination valid at high collision energies. Finally, we verify the universal scaling law by comparison to atomic and molecular experimental data available in the literature. We expect our findings will motivate further experimental work to verify our universal scaling for more complex systems in the absence of experimental data. ARTICLE HISTORY
