    "abstract": "This paper theoretically analyzes the hydrodynamic shape stability problem\nfor sonoluminescing bubbles. We present a semianalytical approach to describe\nthe evolution of shape perturbations in the strongly nonlinear regime of\nviolent collapse. The proposed approximation estimating the damping rate\nproduced by liquid viscosity is used to elucidate the influence of the collapse\nphase on subsequent evolution of the Rayleigh-Taylor instability. We\ndemonstrate that time derivatives of shape perturbations grow significantly as\nthe bubble radius vanishes, forming the dominant contribution to\ndestabilization during the ensuing bounce phase. By this effect the\nRayleigh-Taylor instability can be enhanced drastically, yielding a viable\nexplanation of the upper threshold of driving pressure experimentally observed\nby Barber et al. [Phys. Rev. Lett. 72, 1380 (1994)].",
