Electronic Stopping Power of Matter for Ions

Graphs, Data, Comments and Programs

Last update: December, 2021 (see Updates)


This collection of stopping power measurements includes data published as early as 1928 by Rosenblum, and is continuously updated. The collection, originally created and maintained by Helmut Paul, considers any ion and target combination that is measured and published, including solids (amorphous or polycrystalline), gases, elements or compounds, new materials such as polymers, oxides, silicates, and also biological targets. It deals with the electronic stopping power, assuming that nuclear stopping has been subtracted or is negligible.

Data and graphs can be downloaded from the tables for H, He, Li to Ar, and K to U ions. Detailed information on the content and organization of the database is provided in the Introduction.

Since 2015 the stopping database is maintained by the IAEA Nuclear Data Section. Dr. Claudia Montanari (Universidad de Buenos Aires-CONICET) is responsible for the compilation of data and graphs, and the development of the database. In About you can read about the history of the database and the pioneering work of Helmut Paul. Articles about the database can be found in Literature.
