Charged particle assisted nuclear reactions in solid state environment: renaissance of low energy nuclear physics

TL;DR

This paper reviews electron assisted nuclear reactions in solids, highlighting their unexpectedly large cross sections at low energies, and discusses their potential role in explaining experimental phenomena like nuclear transmutation and the Fleischmann-Pons effect.

Contribution

It provides a comprehensive overview of electron assisted nuclear processes in crystalline solids and proposes their significance in explaining low-energy nuclear phenomena and experimental observations.

Findings

Electron assisted neutron exchange processes may have observable cross sections at low energies.

These processes could explain nuclear transmutation and anomalous screening phenomena.

Analysis of Ni and Li-Ni systems suggests relevance to experimental results like the Rossi E-Cat.

Abstract

The features of electron assisted neutron exchange processes in crystalline solids are survayed. It is stated that, contrary to expectations, the cross section of these processes may reach an observable magnitude even in the very low energy case because of the extremely huge increment caused by the Coulomb factor of the electron assisted processes and by the effect of the crystal-lattice. The features of electron assisted heavy charged particle exchange processes, electron assisted nuclear capure processes and heavy charged particle assisted nuclear processes are also overviewed. Experimental observations, which may be related to our theoretical findings, are dealt with. The anomalous screening phenomenon is related to electron assisted neutron and proton exchange processes in crystalline solids. A possible explanation of observations by Fleischmann and Pons is presented. The possibility of the phenomenon of nuclear transmutation is qualitatively explained with the aid of usual and charged particle assisted reactions. The electron assisted neutron exchange processes in pure $Ni$ and $Li-Ni$ composite systems (in the Rossi-type E-Cat) are analyzed and it is concluded that these reactions may be responsible for recent experimental observations.
