Based on three major anomalous phenomena in 9 yr of research on nuclear reactions in solids, research-ers assume that a resonant tunneling model explains the experimental observation. Using a square-well configu-ration, the maximum resonant tunneling current through the Coulomb barrier is shown to be ofthe order ot 1/θ, while the nonresonant tunneling current is of, the order of 1/θ2 (1/θ2 is the Gamow tunneling factor). The dis-tinction between the resonant tunneling model and the compound nucleus modef is discussed. Particularly, the fon energy band fn the deuteride is fnvoked to generate the necessary fong Zifetime (d+d)x state. This resonant tunneling model might provide a mechanism for low-enerev nuclear transmutation as well.

The cross section of deuteron-triton sub-barrier fusion is calculated using the selective resonant tunneling model with the assumption of a square-well nuclear potential. A complex potential is assumed to describe the absorption inside the nuclear well. The surprisingly good agreement between the theoretical calculation and the experimental data implies that the compound nucleus model might not be applicable to the light-nuclei subbarrier fusion. Instead, the selective resonant tunneling model is proposed.
