In 1990, Helmut Paul started to collect stopping powers for positive ions at the University of Linz. He plotted the data in a way similar to Jim Ziegler's well known collection [1,2], but he added also theoretical curves for comparison. The collection, originally for light ions, was later extended to all ions. With A. Schinner, Paul also produced program MSTAR that predicts stopping powers for ions from 3Li to 18Ar, and they used their program JUDGE to compare stopping tables and experimental data in a statistical manner. Program MSTAR is available from http://www.exphys.jku.at/stopping/ results from JUDGE showing the reliability of theories were published in several papers that are also listed in in http://www.exphys.jku.at/stopping/.
In 2015, the collection has been transferred to Mexico. It treats the electronic stopping power (we assume that "nuclear" stopping has been subtracted, but that need not always be true). It considers ordinary cold matter, not the plasma state. It considers gases and amorphous or polycrystalline three-dimensional solids, elements and compounds. The designations of the theoretical curves are also explained in http://www.exphys.jku.at/stopping/.
Graphs are only shown when there are at least two or three measurements for the same ion-target case, but many more data exist. All the numerical data are shown in folder scsdata.zip which is available at http://www.exphys.jku.at/stopping/
Tables of Optical Oscillator Strengths are also given for a few elements in http://www.exphys.jku.at/stopping/.
