A new electrical hypothesis explaining sonoluminescence,chemical actions and other effects produced in gaseous cavitation

A new electrical hypothesis explaining sonoluminescence, chemical actions and other effects produced in gaseous cavitation is proposed. The hypothesis rests on the internal charge of the bubble and its rapid discharge when compressed. The charge arises from the neutralization of the anions adsorbed into the surface of the bubble because of the adsorption and induced polarization of gas molecules at the interface. In the case of rare gases, the charge formed should increase with the polarizability of the gas and its atomic number. Under rapid compression, charge density may reach disruption gradient at the interface. A microscopic discharge occurs towards the liquid and produces the effects currently observed.
