“…The proposed model describes the system as traceable to a dense solid state plasma leading picnonuclear reactions of proton captures in presence of lattice potentials in the order of 10 1 keV , theoretically predicted to be in the order of 10 keV [14][15] and experimentally observed towards X-Ray measurements (the proposed picture could be also applied to different approaches for estimating the effective screening distance). The calculation results show that the reaction rate estimated on the basis of the experiments [16], in the proposed picture, may be achieved with potentials (and energies) in the lattice in the order of 10 1 keV instead of MeV as in vacuum. The calculated reactivity is in reasonable agreement with the value estimated on the basis of the SIMS analysis performed on hydrogenated Ni thin films [16].…”
