Experiments using CR-39 detectors have shown that energetic particles and neutrons are emitted during Pd/D co-deposition. Using 6 micron Mylar between the CR-39 and the cathode, it has been shown that the majority of the tracks formed have energies on the order of 1 MeV. This conclusion was supported by computer analysis of the pits using the ‘Track_Test' program developed by Nikezic and Yu. In this communication, additional analysis of the chips will be discussed. In particular, it will be shown that the size distribution of the neutron-generated tracks on the back side of the CR-39 detectors indicate that DD and DT fusion reactions are occurring. This is supported by the presence of triple tracks and double tracks on the front surface of the CR-39 as well as the energies of the charged particles as determined in the Mylar experiments. Uses of neutrons for energy production and other applications will be discussed as well.
