The stimulated collision-induced fluorescence (SCF) at wavelengths of 551.9, 606.3, and 611.1 nm was observed from XeCl-laser pumped barium vapor for the first time. They correspond to the following transitions of barium atoms respectively: 6s6d3D2-6s6p3P1, 5d6p2-6s5d3D3, and 5d6p2P1-6s5d3D2. The possibility of exis-tance of the barium spin-forbidden transition 6s7d1dD-6s6p3P2 was proposed and discussed.
