Features of the Formation of Correlated Coherent States and Nuclear Fusion Induced by the Interaction of Slow Particles with Crystals and Free Molecules

Abstract

The results of the experiments, where the intense generation of alpha particles with an energy of about 8.6 MeV was observed at the interaction of 400–600-eV slow protons with a thin lithium foil or lithium vapors, have been analyzed. It has been shown that the high efficiency of these reactions at such a low energy cannot be explained within standard models of accelerator nuclear fusion. A model has been proposed and considered for the initiation of these reactions by correlated coherent states of protons, which are formed at the electrostatic interaction of these moving particles with the fields of surface lithium atoms in a solid target, as well as with atoms in molecules of lithium vapor. It has been shown that the formation of such states is accompanied by a sharp increase in short-term fluctuations of the energy of protons, which are due to the Schrödinger–Robertson uncertainty relation, to an amplitude of 30–80 keV. The calculation has shown that the optimal energy of the initial motion of protons, at which these processes occur and the probability of the (Li, p) reactions involving these protons is large, is near 500 eV in complete agreement with the experimental data.
