摘要：

Differential cross sections for electron impact on excited state barium atoms have been measured for 20 eV incident electron energy and scattering angles of 5.5 degrees, 9 degrees, 13 degrees and 16 degrees. Results for the excitations (... 6s6p P-1(1)) -> X are presented with X (... 6s7s(1)S(0)), (... 6s7p(1)P(1)), (... 5d(2 1)D(2) +... 5d6p(1)D(2)), (... 5d(2) P-3(2)) and... (6s6d D-1(2)). Comparisons are made with existing theoretical results calculated in the convergent close coupling formalism and the unitarized distorted wave approximation.
