We have used convergent close-coupling method and first-order many-body 
theory to calculate integerated cross sections for elastic scattering and 
excitation of the 5d$^2$~$^1$S, 6s6p~$^1$P$_1$, 6s7p~$^1$P$_1$, 6s8p~$^1$P$_1$, 
6s5d~$^1$D$_2$, 5d$^2$~$^1$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 
by electron impact on the ground state of barium at incident electron energies 
from 1 to 1000~eV. These results have been combined to produce a recommended set of 
integerated cross sections.
