Cross sections and characteristics of electron scattering by calcium, strontium, and barium atoms
Romanyuk N. I. , Shpenik O. B., Zapesochnyi I. P.
The total cross sections for scattering of electrons by calcium, strontium, and barium atoms were determined for the first time in the energy region 0.1-10 eV, using a modified electron-trap method and atomic-beam modulation.
