Nuclear reactions in condensed matter: a theoretical study of d-d reaction within palladium lattice by means of the coherence theory of matter

摘要

In the last decades, an indisputable experimental evidence was built up for (Low Energy Nuclear Reaction) phenomena (LERN) in heavy hydrogen loaded systems. Actually, the real problem is that the theoretical statements of LERN are unknown; in fact, it doesn't exist a new branch of science yet. The aim of this work is to analyse the deuteron-deuteron reactions within palladium lattice by means of Preparata model of palladium lattice. Furthermore in order to theoretically demonstrate the possibility of cold fusion, this work shows the occurrence probability of fusion phenomena according to more accurate, but not claimed, experiments. Further, we focus on tunneling the Coulomb barrierrnbetween two deuterons. Analysing the possible contributions of lattice on improving the tunneling probability, we will find that there is a real mechanism through which this probability could be increased: this mechanism is the screening effect due to d-shell electrons of palladium lattice. Finally the good agreement between theoretical and experimental results proves the reality of cold fusion phenomena and the reliability of our model.
