Experimental electronic stopping cross section of transition metals for light ions: Systematics around the stopping maximum

Abstract: Electronic stopping cross sections of different transition metals (Nb, Pd, Ta, and Pt) for light ions have been experimentally determined in a wide energy range. We performed relative measurements using different backscattering geometries for protons (from 50 to 5000 keV) and helium (from 80 to 10 000 keV). Data are compared to values from the literature, as well as to the widely used semiempirical (SRIM) and modeling (DPASS) approaches. The magnitude and energy dependence of the deduced stopping power at ener… Show more

“…Our measurements of the stopping power of protons on Pt agree with recent Moro, Bauer, and Primetzhofer [60] measurements, which were at variance by about 20% with previous measurements and SRIM calculations. The theoretical model TCS-Penn agrees with our stopping measurements for energies lower than 80 keV (in agreement with Refs.…”

“…Both results for sample A and B are in good agreement with the most recent ones from Refs. [50,60] measured by time-of-flight MEIS and ICRU49 [53] values. However, they are about 20% larger than other previous experiments and SRIM [54,55] values.…”

“…But in general, there is a rather good agreement with most of the experimental data in the whole energy range in our study. The behaviour around the stopping maximum is depicted in the insets of figure 2, where it can be seen that the agreement of our calculated stopping powers with the most recent experimental data [32][33][34][35][36][37][38][39][40][41][42] is particularly good. Stopping power of platinum (left panels) and gold (right panels) for protons (upper panels) and alpha particles (lower panels).…”
