Dr. Robert T. Bush of California State Polytechnic University has suggested that when a palladium lattice is fully occupied by deuterons, conditions are favorable to support laser-like actions where the deuteron-loaded lattice supports a type of resonating phenomena in which the probability of a traveling or "hopping" wave-like deuteron fusing with a target deuteron is increased significantly.
This may also be caused by the possibility of plasma oscillations of the D-shell. Also the theory that deuterons (protons) exist in deep energy wells may not be valid because the protons appear to be mobile in a similar state as classical oscillators. Bush's theoretical model accounts for the heavy water heat effect and light excess heat effect from cold fusion. It provides a unique and highly novel mechanism to sufficiently enhance tunneling through the Coulomb barrier, as well as incorporating the role of lithium in electrolytic experiments.
