SOME LOW-ENERGY ATOMIC STOPPING CROSS SECTIONS

Abstract
The electronic stopping cross sections for protons in aluminum are reported in the energy interval 10 < E < 70 keV. Stopping cross sections below 150 keV in carbon targets for projectiles with [Formula: see text], and in aluminum targets for [Formula: see text] are reported also. The results are compared with theory and show reasonable agreement. The previously reported periodic dependence of Se on the atomic number of the projectile is also evident in the present results.
