Local coherence, condensation and nuclear reaction of neutrons at crystal boundary of metal hydrides and deuterides

Using a concept of the neutron Bloch wave in the one-body approximation presented previously, possibilities of the following effects in boundary regions of crystals including hydrogen isotopes are pointed out: occurrence of local coherence, formation of a neutron Cooper pair, condensation of neutrons, formation of neutron drop and an effective nuclear reaction of a nucleus with thermal neutrons. It is shown that these new states and reactions will have strong effects on solid state-nuclear physics in metal hydrides (deuterides). The stochastic occurrence of localized nuclear reactions observed in CF experiments is explained by these properties of the trapped neutron. The possible application of the nuclear reactions in metal hydrides is discussed.
