Abstract
The range of Ar in Be and C, of Kr in Be, C, and Al, and of Xe in Be, C, and Al has been measured in 100-keV steps from 500 keV to 2 MeV with an accuracy varying from ±10.1 to 3.2%. The range of Xe in V, Ni, and Cu has been measured in 250-keV steps from 500 keV to 1.75 MeV with an accuracy of ±11.4 to 5.7%. Seven of the 11 sets of measurements agree to within 9% of the theory due to Lindhard, Scharff, and Schiøtt, with the best agreement in the energy region where electronic stopping is roughly equal to nuclear stopping. The measurements on Ar in Be and C are lower than the theory by 10-18% until a shell-structure correction of Ormrod, MacDonald, and Duckworth is applied, and then excellent agreement is obtained. The measurements on Xe in Ni and Cu are lower than the theory by 8-24%. Proton-stopping cross sections in V at 559, 1776, and 1984 keV are reported.
