Models for Anomalies in Metal Deuterides

There have been a great many claims for anomalies in experiments on metal deuterides, including excess heat, heat correlated with helium, slow tritium, low-level dd-fusion, and particle emission not produced by dd-fusion reactions. We have studied models that involve phonon exchange with a highly excited phonon mode in the case of fusion reactions and disintegrations. We have recently generalized the approach to include phonon- mediated nuclear excitations. The resulting models may be applicable to experiments in which evidence for penetrating radiation is found, as well as to some transmutation effects.
