摘要

TiH2 and TiD2 thick targets were bombarded with 170 keV protons and with 170 keV deuterons. Charged particles from nuclear reactions were observed by means of a surface barrier particle detector shielded by an energy absorbing foil. Deuteron irradiation of TiD2 produced these observations: copious similar to 2.5MeV neutrons and similar to 3MeV protons from direct d-d reactions, gamma rays from p,gamma and n,gamma reactions, similar to 14MeV protons from the secondary d(He-3,p)alpha reaction, and an anomalous, broad energy distribution proton signal between similar to 5-11 MeV. Our observations confirm the anomalous proton emission at a rate similar to 4 x 10(-5) of the d-d fusion rate.
