N2 - Oscillator strengths have been determined for 23 transitions from the ground level of Ba relative to that of the resonance line by the hook method. The results are in good agreement with other experimental values. Rate coefficients of He-, Ar- and Kr-induced broadening have been measured for 6 s2 1 S0 -6 s n P1 ( n =7 to 10), 6 s2 1 S0 -5 d n P1 ( n =6 and 7), and 6 s2 1 S0 -5d7p 3D1 and 3P1 by the total absorption method. We find that, generally, the rate coefficient increases monotonously to its maximum value and then decreases with the effective principal quantum number of the upper level relative to the first ionization limit. For 6 s2 1 S0 -5d7p 3P1 and 3D1, the rate coefficients deviate from this tendency and show minimum values. This singularity is explained qualitatively on the basis of the Fermi potential model by taking account of the configuration mixing.
