The following table (for particles with atomic number up to z = 28 impinging perpendicularly to the absorber surface) was obtained using the "SRIM Module.exe" included in SRIM 2013 code and implemeted in the sr-niel website here.

The kinetic energy thresholds were derived from SRIM data using an interpolation procedure.

The particle rigidity (R) is expressed in GV and is expressed as (e.g., see Eq. (8.94) at pag 642 of Leroy and Rancoita (2016)):

formula

where c is the speed of light, z is the particle atomic number, e is the electron charge and p is the incoming particle momentun in GeV/c.
