Study of the tunneling effect within lattices with cubic structure on varying temperature

摘要

In this theoretical study, it is underlined that the presence of micro-cracks in the lattice structure increases the probability of tunneling effect between two deuterons by some orders of magnitude with respect to non-deformed lattices. We have derived an expression to compute the tunneling probability within a micro-crack, and hypothesized a D~+_2-D~+_2 binding mechanism. Finally, the overall indications provided by these theoretical simulations appear to suggest that the deformation of the crystalline lattice, at varying temperature, seems able to influence the process of tunneling between the deuterons in the metal, while the forced loading with D_2 has, in general, no evident positive effects in pure metals, but in some cases could, on the contrary, condition the phenomenon negatively.
