Physical Review B 26, no. 5: 2335-2340. doi:10.1103/physrevb.26.2335.0163-1829http://nrs.harvard.edu/urn-3:HUL.InstRepos:29407051A critical analysis of channeled-ion energy-loss experiments is presented with the goal of commenting on the presence of the Barkas effect of Z31 corrections to the stopping power. Accurate charge-density values are obtained for silicon and used to evaluate Bloch and straggling effects in the data. The remaining contributions to the data show a clear Z31 dependence that can be explained with an electron-gas model for the Barkas effect.en-USJournal Article2016-11-1810.1103/PhysRevB.26.2335
