N2 - Absorption method has been applied to observe the collision-induced dipole transitions associated with the optically forbidden transitions 6s 21S0–6p21D2, -6s9d 1D2, -6s10d 1D2, and -5d8p 1D2 of barium in argon, krypton or xenon atmosphere. The effective oscillator strength per unit rare-gas density is obtained to be, e.g., for 6s2–6s9d, 3.6×10−24, 2.0×10−23, and 5.8×10−23cm3for argon, krypton, and xenon, respectively. A correlation is found between the effective oscillator strength and the scattering length of the rare-gas atoms for electrons. This is explained from a model in which an adjacent P state mixes into the D state due to the interaction potential between the loosely-bound valence electron and the rare-gas atom.
