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(21)S, 6s6p(1)P(1), 6s7p(1)P(1), 6s8p(1)P(1), 6s5d(1)D(2), 5d(21)D(2), 6S6d(1)D(2), 6p5d(1)F(3), 6s4f(1)F(3), 6p5d(1)D(2), 6s6p(3)P(0,1,2), 6s5d(3)D(1,2,3), and 6p5d(3)D(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. [S1050-2947(99)02912-1].
