Results of the experimental study of excitation of transitions of singly ch
arged barium atoms in collisions of low-energy monokinetic electrons with b
arium atoms are presented. Regularities of the behavior of cross sections f
or excitation in spectral series of BaII are found. The results are compare
d with other authors' results. (C) 2000 MAIK "Nauka/Interperiodica".
