My name is Helmut Paul (b. 1929). Since 1990, I have been collecting data on stopping powers for light ions, while my colleagues at the University of Linz measured them. I plotted the data versus energy/nucleon, compared them to each other and to the theoretical or semi-empirical curves available in the literature. Together with A. Schinner, I produced a program MSTAR that will predict stopping powers for ions from 3Li to 18Ar (most recent version 2004). Our program JUDGE is used to compare stopping tables and experimental data in a statistical manner (see, e.g., papers below).
In recent years, the collection has been enlarged to include also heavier ions. 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 solids. You are welcome to look at the plots, to use the data collection and to use program MSTAR. Although my collection is large, it is probably not complete. I keep it up to date, but I hope another expert will take over soon.
Since 2009, tables of Optical Oscillator Strengths have been listed for several elements, see below.
