Inelastic and superelastic scattering of 30- and 100-eV electrons by laser-excited 6s6p/sup 1/P and subsequent cascade-populated 6s6p/sup 3/P, 6s5d/sup 1/D, and 6s5d/sup 3/D Ba atoms have been observed for the first time. Absolute differential cross sections for the singlet and relative scattering intensities for the triplet species have been determined in the 5/sup 0/--20/sup 0/ angular region. Under the present conditions excitations dominate over de-excitations.
