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.

The essence of the low-energy transmutation process is that several billion electrons can be formed into a stable cluster; that this cluster of electrons can pick up and carry positive ions; and that the combined charge cluster (typically 100 billion electrons and one million ionized hydrogen atoms) can be accelerated by a voltage and create nuclear reactions in a target material.
First, nuclear reactions occur in a slowly expanding wavefront, producing iron and similar elements.
