Spectra of sonoluminescent rare-Gas bubbles
1Department of Physics, The University of Texas at Austin, Austin, Texas 78712, USA.
Abstract:
Sonoluminescence spectra of the heavy rare gases are calculated by combining the Hilgenfeldt et al. model of sonoluminescence [Phys. Fluids 11, 1318 (1999)] with quantum line-shape calculations of electron-neutral-atom bremsstrahlung spectra [L. Frommhold, Phys. Rev. E 58, 1899 (1998)]. Good agreement between theoretical and experimental spectra is obtained by choosing values of the ambient radius R0 and acoustic pressure amplitude P(a) that are compatible with diffusive equilibrium calculations.
