The dynamic interaction observed at cryogenic temperatures in PdDx (x < 1) lattices is interpreted to be the result of interstitial solute deuterons jumping from the tetragonal sites to the octahedral one along the [111] directions and electrostatic attraction due to the charge transfer in the chains; i.e., an alternating tetrahedral-octahedral site arrays with the help of the electron-phonon charge-density wave coupling. The generation of heat may be associated with the collective electrons derived from the palladium atoms and neutral pions between deuterons.
