Spectrum of barium dimer and its contribution to transitions of barium atom
With the experiments of dye laser shining on Ba generated in a heat pipt oven, we find in the spectrum ranging (from 420.0 to 440. 0nm) a broad-band structure and several Ba lines with transitions not coming from the ground state of Ba. A probable dynamics is given with the hypothesis of the dissociation of Ba dimer. The broad-band structure is ascribed to the absorption peak of Ba dimer.
