Anomalous neutron emission from metal-deuterium system

We have observed anomalous neutron emission from metals containing deuterium, suggesting the occurrence of nuclear fusion at low rates under unusual conditions. The novel phenomenon has been corroborated in collaborative experiments at the Gran Sasso Laboratory and at the Los Alamos National Laboratory. The purpose of this paper is to review experimental evidence that neutron emission is correlated with non-static conditions in metal-deuterium systems, and to posit the conjecture that cold fusion is associated with the formation of metallic deuterium.
