Abstract

Measurements for the differential scattering of protons by helium and argon as a function of scattering angle and impact energy are presented for the range 3-20 keV and 1°-5° laboratory angle. The measurements are of the sum of elastic, inelastic, and charge-changing collisions. Comparison is made with two classical calculations, one employing the Bohr screening length, the other employing separate screening lengths for each electronic shell. For argon, the data are in significantly better agreement with the calculation employing separate screening lengths for each electronic shell.
