标题： Integral cross sections for electron scattering by ground state Ba atoms

摘要： 我们使用了收敛闭合耦合方法和单位化的一阶多体理论，计算了在入射电子能量从1到1000 eV时，钡原子基态受电子碰撞的弹性散射和动量转移的积分截面，以及激发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}和6p5d^3D_2 状态的积分截面，以及电离和总散射的积分截面。 这些结果和所有可用的实验数据结合在一起，生成了一组推荐的积分截面。 显示英文摘要

摘要： 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.
