LENR – Nuova pubblicazione e nuova terminologia: i ‘Discrete Breathers’

Lenr_6Mentre siamo tutti in attesa di leggere il report che terze parti indipendenti stanno predisponendo sull’E-Cat, la rivista Arxiv.org ha appena pubblicato un interessante articolo scritto da Vladimir Dubinko del NSC Kharkov Institute of Physics and Technology, in Ucraina.
Questa pubblicazione, segnalata da Andreas Moraitis sul blog tenuto da Andrea Rossi sul Journal of Nuclear Physics, e’ intitolata “Low energy nuclear reactions driven by discrete breathers” e, oltre ad avanzare una nuova teoria su cio’ che avviene durante le LENR, introduce questi nuovi termini, Discrete Breathers (oppure DBs), nel descrivere le ‘vibrazioni anarmoniche della griglia (lattice) a grande ampiezza‘.
Questo e’ l’abstract:

A new mechanism of LENR in solids is proposed, which is based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete breathers (DBs). In particular, so called gap DBs, which can arise in diatomic crystals such as metal hydrides, are argued to be the LENR catalyzers. The large mass difference between H or D and the metal atoms provides a gap in phonon spectrum, in which DBs can be excited in the H/D sub-lattice resulting in extreme dynamic closing of adjacent H/D atoms required for the tunneling through nuclear Coulomb barrier. DBs have been shown to arise either via thermal activation at elevated temperatures or via knocking atoms out of equilibrium positions under non-equilibrium gas loading conditions, employed under radiolysis or plasma deposition methods. The DB statistics in both cases is analyzed and simple analytical expressions for the cold fusion energy production rate are derived as the functions of temperature, ion (electric) current and material parameters. For the first time to our knowledge, the derived expressions describe quantitatively the observed exponential dependence on temperature, linear dependence on the ion current as well as the role of external triggering and small dimensions of nuclear active particles.
Anche Andrea Rossi pare interessato a questa nuova teoria, e giudica positivamente l’uscita di questa pubblicazione.
