Anomalous enhancement of three-body deuteron fusion reactions was observed by low-energy D+ ion beam implantation experiment with titanium-deuteride (TiDx: x = 1.4) using a E-E charged-particle spectrometer. The enhancement ratio was ~1026, compared with the traditional theory estimation for a beam/target interaction of the random nuclear reaction process. Two characteristic charged particles of 4.75-MeV helium (3He) and 4.75-MeV triton from the reaction channel of 3D → t + 3He + 9.5 MeV were identified by the analysis of measured one- and two-dimensional spectral data. An experimentally obtained 3D fusion rate was on the order of 102 fusion/s, which is a surprisingly large value. Strong enhancement of 4D fusion was also indicated by higher-energy alpha-particle spectra.
A possible explanation is given by the hypothesis of simultaneous multibody fusion induced with the coherent dynamic motion of three to four deuterons and many electrons around special focal points in a metal-deuteride lattice. The observed enormous enhancement of the 3D fusion rate suggests the possibility of "nuclear fusion in solid at room temperature," i.e., so-called cold fusion, which may open a new physics field between nuclear physics and solid-state physics.
