Tunneling Effect Enhanced by Pd Screening as Main LENR Mechanism: A Brief Theoretical Impression

In this paper the main features of tunneling travelling are illustrated between two deuterons within a lattice. Considering the screening effect due to lattice electrons we compared the d-d fusion rate evaluated from different authors assuming different screening efficiency and different d-d potentials. Then, we proposed an effective potential which describes very well the attractive contribution due to plasmon exchange between two deuterons and by means of it we will compute the d-d fusion rates for different energy values.
