Neutron Emissions from Deuterided Metals

Evidence is presented for neutrons emanating from partially deuterated titanium foils (TiDx) subjected to non-equilibrium conditions (charged particle results appear in a separate paper in this proceedings). Two types of deuteriding and varied currents were employed to produce the non-equilibrium conditions within the foils, and emissions lasted over long durations. Experiments were conducted in a deep underground tunnel having significant rock overburden to diminish cosmic backgrounds. Subtracting background rates and taking into account detector efficiency, we found the highest net yield to be 57 ± 13 counts/hour. Yields for all runs are reported and the theoretical fusion reaction defined. Totaling all experiments, reproducibility was 40%.
