Phonon-induced hopping rate enhancement in the Pd–D system

Abstract

This paper shows that an exact calculation for transition probability can makesome systems deviate seriously from Fermi’s golden rule. The paper also showsthat the corresponding exact calculation of the phonon-induced hopping rate for adeuteron in the Pd–D system plus many-body electron screening, proposed byIchimaru, can explain experimental factors observed in the Pd–D system. It alsopredicts that the perfect and low dimensional forms of the Pd lattice are veryimportant factors for the phonon-induced hopping rate enhancement of deuteronsin the Pd–D system.
