Recently Taleyarkhan et al. presented evidence of the deuterium-deuterium (DD) fusion reactions in a multibubble sonoluminescent (MBSL) system. In this article, the results of the search of evidence of DD reactions in a single cavitation bubble luminescent (SCBL) system are presented. A single bubble is produced using a Nd:YAG laser in CDCl3 and D2O media varying the liquid temperature betweenet al. presented evidence of the deuterium-deuterium (DD) fusion reactions in a multibubble sonoluminescent (MBSL) system. In this article, the results of the search of evidence of DD reactions in a single cavitation bubble luminescent (SCBL) system are presented. A single bubble is produced using a Nd:YAG laser in CDCl3 and D2O media varying the liquid temperature between3 and D2O media varying the liquid temperature between −50◦C to 22◦C. A special low neutron flux detection system was developed in order to minimize false signals due to background noise. No neutrons attributable to DD fusion reactions were detected.50◦C to 22◦C.
