Abstract: Two stages of luminescence development have been established during intense flows of hydraulic oil in a narrow channel: a precursor and the subsequent main luminescence pulse. Luminescence stages are associated with gaped momentum states (GMS) during the formation of collective localized shear modes.

Keywords: cavitation, sonoluminescence, collective modes.
