In the following tables you can find the electronic stopping power plotted versus the projectile energy per nucleon. The reference codes are explained in the list of all data references, and the curve designations in the list of stopping power tables and programs. The figures can be download as image and also the origin graphs. The experimental data is also available as ascii files.
To download ALL the experimental data (all projectiles and targets) click here. To see the list of data and references for heavier ions click here. Generally, graphs are shown if at least two or three set of data from different publications are available for the particular ion-target combination. So the data files are more complete than the graphs.
For ions up to Ti, there are also "universal plots" showing all the data obtained for a same projectile. These data are divided by the electronic alpha stopping powers from ICRU Report 49, and normalized in such a way that they approach unity at high energy.
At present, graphs are available for the following projectiles and targets:
