“…During the search for "Cold Fusion" spurious pulses were observed. Abnormal background level fluctuations 100 times the normal mean value were detected [20]. The reason is not fully understood but it is probably related to electrical break-down in the insulating materials.…”

“…Besides electrolytical loading, deuterium was also introduced into the metal lattice by applying a hydrostatic pressure of up to 100 bar [5,6,12]. In some cases, it was pointed out that it is essential to reach deuterium concentrations in the lattice that are well above the saturation concentration, which is typically two deuterium atoms per metal atom.…”

In the search for ‘cold fusion’ reactions in solids loaded with deuterium atoms at high concentration, ion implantation has been used as a means to reach the required high deuterium concentration in the lattice. In the present investigations, 300 eV to 6 keV D+ ions were injected into 3 μm thick titanium foils at room temperature and at 140 K. The protons from the D(d,p)T reaction were monitored using a solid state detector with a large solid angle, both during and after implantation. After implantation of deuterium in the titanium foil up to saturation, i.e. with about 1.8 deuterium atoms per titanium atom at room temperature, the possible fusion reaction rate at equilibrium was determined over a period of 65 h. The measured count rate was within the limits of the natural background, and an upper limit of 1 × 10−23 per deuterium pair per second was established. During implantation of deuterium at energies between 3 and 6 keV, the count rate is dominated by reactions of the incident energetic deuterons with deuterons already implanted in the foil. The D-D reaction cross-sections, evaluated at 140 K, follow closely those obtained by extrapolation of the Gamow function to low energies. During implantation of 300 eV D+ ions, no counts from the D(d,p)T reactions were monitored, showing that even under extreme conditions of non-equilibrium the possible ‘cold fusion’ reaction rate is smaller than the background count rate.

Deuterium ( 2 H or D) the heavier, stable isotope of hydrogen ( 1 H) occurs in nature, and is always present in all hydrogen‐containing compounds. Deuterium oxide, known as heavy water, is the most important deuterium compound. Heavy water differs from ordinary water in structure of the liquid phase, in nuclear spin, ionic equilibria, and in various spectroscopic properties. Kinetic isotope effects occur in chemical reactions involving bond rupture of H and D. This effect in hydrogen exchange between water and hydrogen sulfide is the basis for the most important separation process for large‐scale deuterium production. Infrared absorption is the method of choice for the analysis of heavy water. Deuterium has far‐reaching biological effects, and it is possible to grow living organisms in which all of the hydrogen normally present is replaced by deuterium. The nuclear properties of deuterium are such that heavy water is the most efficient neutron moderator known for nuclear fission reactors. Deuterium is also important in nuclear fusion technology.
