Electronic stopping power of axial channeled Li ions in Si crystals

We report measurements on the electronic stopping power of 7 Li ions along the 〈1 0 0〉 Si direction in the energy region between 1 and 8 MeV. The measurements were carried out using the standard RBS/Channeling technique with SIMOX targets. The results show that the stopping power decreases for increasing energies, from 48 eV/A at 1 MeV down to 19 eV/A at 8 MeV. The general features obtained for the stopping power of 7 Li resemble those obtained for He ions measured previously.
