"The presence of three alpha-particle tracks outgoing from a single point is diagnostic of the 12C(n,n′)3alpha carbon breakup reaction and suggests that DT reactions that produce ≥9.6 MeV neutrons are occurring inside the Pd lattice. To our knowledge, this is the first report of the production of energetic (≥9.6 MeV) neutrons in the Pd–D system."
