Abstract
The simplest interaction between sound and quantized superfluid vortic es is investigated both analytically in the Born approximation and num erically, using the nonlinear Schrodinger equation. Compared with the scattering by a classical vortex, the quantum result reflects the stru cture of the vortex core and has an extra phase shift. The order of ma gnitude of the effects suggests possible experiments in rotating super fluid helium.
