Integral cross sections for electron scattering by ground-state Ba atoms

We have used the convergent close-coupling method and a unitarized first-or der many-body theory to calculate integral cross sections for elastic scatt ering and momentum transfer, for excitation of the 5d(21)S, 6s6p(1)P(1), 6s 7p(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. The se results and all available experimental data have been combined to produc e a recommended set of integral cross sections. [S1050-2947(99)02912-1].
