Calculations of Stopping Cross Sections for 0.8- to 2.0-MeV Alpha Particles

Abstract

Calculations of $\ensuremath{\alpha}$-particle stopping cross sections based on the theories of Lindhard et al. using the Hartree-Fock-Slater atomic-charge distribution provide generally good agreement with previously obtained experimental results. In particular, the calculations are helpful in understanding the structure which results when, for fixed energy of the $\ensuremath{\alpha}$ particle, the stopping cross section is plotted against the atomic number of the stopping medium.
