Integral cross sections for electron scattering by ground state Ba atoms
We have used the convergent close-coupling method and a unitarized
first-order many-body theory to calculate integral cross sections for elastic
scattering and momentum transfer, for excitation of the 5d^2 ^1S, 6s6p^1P_1,
6s7p^1P_1, 6s8p^1P_1, 6s5d^1D_2, 5d^2^1D_2, 6s6d^1D_2, 6p5d^1F_3, 6s4f^1F_3,
6p5d^1D_2, 6s6p^3P_{0,1,2}, 6s5d^3D_{1,2,3}, and 6p5d^3D_2 states, for
ionization and for total scattering by electron impact on the ground state of
barium at incident electron energies from 1 to 1000 eV. These results and all
available experimental data have been combined to produce a recommended set of
integral cross sections.Comment: 47 pages, 8 tables, 25 figure
