Calculated diffusive equilibriums in the p a– R 0 plane (a positive slope indicates the stability) for Xe (a) and He (b) bubbles in 20-°C water with f = 34 kHz. The bubbles on (pentagons) and near (stars) the curve for relative gas concentration c ∞/ c 0 = 0.004 or c ∞/ c 0 = 0.003 are calculated to obtain the FWHMs as a function of the relative SBSL intensity.
