The dependence of the intensity of subharmonic 1/2, of the sonoluminescence and of the thresholds for the emission of the subharmonic 1/2 and of light on the concentration of solutions of a tensioactive substance in distilled water has been obtained by using the pulsed cavitation technique. The weight concentration was varied from 10-3 to 10-6. There is a minimum in each of the incipient thresholds at a concentration of about 10-5. The subharmonic 1/2 emission indicates a larger number of bubbles in the solutions than in distilled water but this does not influence the intensity of the emitted light very much.

Abstract
The dependence of the intensity of subharmonic 1/2, of the sonoluminescence and of the thresholds for the emission of the subharmonic 1/2 and of light on the concentration of solutions of a tensioactive substance in distilled water has been obtained by using the pulsed cavitation technique. The weight concentration was varied from 10-3 to 10-6. There is a minimum in each of the incipient thresholds at a concentration of about 10-5. The subharmonic 1/2 emission indicates a larger number of bubbles in the solutions than in distilled water but this does not influence the intensity of the emitted light very much.File in questo prodotto:
