Collapse of ultrasound bubbles in superfluids leads to the nucleation of vortex rings. Using the Gross-Pilaevskii equation for a uniform condensate we elucidate the various stages of the vortex formation and establish conditions necessary for the vortex nucleation after collapse of an oblate moving bubble. In the case of a stationary spherically symmetrical bubble we calculate the vortex line length as a function of time after collapse. © 2005 Springer Science+Business Media, Inc.
