Table 3 Account on availability of the stopping powers data for selected elements

Element	H ions	He ions
Be	No data below 10 keV – no reliable data below 1 MeV.	No data below 200 keV.
C	High number of datasets	High number of datasets; limitations at low energies.
Mo	No data below 50 keV – data spread in the stopping maximum.	Only one low-energy dataset – spread in the stopping maximum.
W	Only one dataset below 100 keV.	Only one dataset below 300 keV; two datasets differing by 10% at classical IBA energies.
