EXCITED STATES OF NUCLEONS IN A NUCLEUS AND COLD FUSION PHENOMENON IN TRANSITION-METAL HYDRIDES AND DEUTERIDES

摘要

The interaction between a neutron in a nucleus at a lattice point (in a lattice nucleus) and another neutron in a different lattice nucleus mediated by a proton (or denteron) at an interstitial site is formulated. The interaction between neutrons through the interstitial protons (or deuterons) could be called the super-nuclear interaction for its long-range nature even if the strength may be extremely small compared with neutron-neutron interaction by the nuclear force in a nucleus. If the neutrons are in an excited state of the nucleus with a wave function with larger orbits than that of the ground state, the interaction becomes considerable to make the excited states form a rather wide band (neutron valence band) similar to valence bands of electrons in semiconductors. Possible influences of the super-nuclear interaction on the nuclear reactions in solids are discussed.
