nu·cle·ar re·ac·tion

the interaction of two atomic nuclei or of one such with a subatomic particle, or of the subatomic particles within an atomic nucleus, resulting in a change in the nature of the nuclei concerned or in the energy content of the nuclei or both, usually manifested by transmutation (accompanied by emission of alpha-, beta-, and/or gamma-rays) or by fission or fusion of the nuclei.

Editors Marwan, a chemist based in Germany, and California-based Krivit (editor, New Energy Times) begin with an introduction to the terminology and a history of this controversial field, which they state was labelled erroneously as "cold fusion" when introduced in 1989, but is more accurately identified as low energy nuclear reactions (LENR), in the field of condensed matter nuclear science.
