    "abstract": "In a companion paper [quant-ph/9904013] we have investigated several\nvariations of Schwinger\u0027s proposed mechanism for sonoluminescence. We\ndemonstrated that any realistic version of Schwinger\u0027s mechanism must depend on\nextremely rapid (femtosecond) changes in refractive index, and discussed ways\nin which this might be physically plausible. To keep that discussion tractable,\nthe technical computations in that paper were limited to the case of a\nhomogeneous dielectric medium. In this paper we investigate the additional\ncomplications introduced by finite-volume effects. The basic physical scenario\nremains the same, but we now deal with finite spherical bubbles, and so must\ndecompose the electromagnetic field into Spherical Harmonics and Bessel\nfunctions. We demonstrate how to set up the formalism for calculating Bogolubov\ncoefficients in the sudden approximation, and show that we qualitatively retain\nthe results previously obtained using the homogeneous-dielectric (infinite\nvolume) approximation.",
