With the progress of cryogenic engineering, unsteady behavior of cavitation vapor bubble collapse in low temperature liquids has been within our scope of great interest. In this paper, phenomena of pure vapor bubble collapse and rebound in low temperature R-12 liquid compressed by the reflected shock wave are treated. The rebound of collapsed bubble in low temperature range is visualized by shadowgraph method using high speed frame camera (lmacon-790) and pulse light. Observed behavior of bubble in liquid R-12 is compared with numerical solution that calculated from Rayleigh-Plesset differential equation. As the results, rebound of vapor bubbles in low temperature liquid and strong spherical shock wave emission are visualized.
