A series of experiments has been performed to determine whether nuclear fusion processes occur in palladium rods that have been electrochemically charged with deuterium. With a variety of metal-lurgical pretreatment procedures and different electrolytes, no evidence has been obtained for any excess enthalpy, neutron, gamma ray, tritium or helium production during electrolysis of D20 with palladium cathodes. 
Search for cold fusion induced by electrolysis in palladium
SummaryA search for electrochemically induced cold fusion in palladium has been carried out in the Gran Sasso Underground Laboratory in order to suppress the background due to environmental neutrons.
Upper bounds on 'cold fusion' in electrolytic cells
Experiments using three different calorimeter designs and high-efficiency neutron and γ -ray detection on a wide range of materials fail to sustain the recent claims of cold fusion made by
A search for particle emission from a gas-loaded deuterium-palladium system in the alpha-beta phase
Neutron and proton emission due to possible solid state fusion events is monitored from a palladium sample loaded with deuterium gas to atomic fractions up to 0.7. Most of the experimental runs show
Neutron and gamma-ray emission from palladium deuteride under supercritical conditions
This paper reports on palladium which is exposed to pressurized deuterium gas at 60 atm and 198 K and the temperature is cycled up to 593 K, beyond the critical point for palladium deuteride. Two
Concerning the detection of neutrons and γ-rays from cells containing palladium cathodes polarized in heavy water
SummaryIt is shown that neutrons generated in «cold fusion» cells can be detected following thermalization by means of high-resolution spectroscopy of the γ-rays generated by the (n, γ) reaction in

This paper discusses recent highly reproducible results of tritium production by deuterium-deuterium (D-D) fusion from gas/solid-state fusion experiments in terms of a surface fusion mechanism.
An attempt to detect fracto-fusion during microwave irradiation of D2O loaded silica gel
Neutron emission has been examined in a system in which the recently reported phenomenon of fracto-fusion might be occurring. No positive evidence has been obtained for cold fusion. The upper limit
Review of Experimental Observations About the Cold Fusion Effect
AbstractThe experimental literature describing the cold fusion phenomenon is reviewed. The number and variety of careful experimental measurements of heat, tritium, neutron, and helium production


Observation of cold nuclear fusion in condensed matter
When a current is passed through palladium or titanium electrodes immersed in an electrolyte of deuterated water and various metal salts, a small but significant flux of neutrons is detected. Fusion
Calculated fusion rates in isotopic hydrogen molecules
COLD fusion occurs when two nuclei with very small relative energy tunnel through their mutual Coulomb barrier to initiate a nuclear reaction. The phenomenon is well studied in muon-catalysed
Mechanisms of Hydrogen Producing Reactions on Palladium II . Diffusion of Electrolytic Hydrogen through Palladium
The rate of diffusion of hydrogen through several thicknesses of palladium for varying current densities was measured. The relationship between the diffusion current and the total polarizing current
Two innocent chemists look at cold fusion
The authors propose that the large energy release reported in the experiments of Fleischmann, Pons, and Hawkins may be the consequence of {sup 2}H fusion accelerated through screening by neighboring
Experimental Electrochemistry for Chemists
The goal of this book is to outline the basic principles and modern methodology of electrochemistry, in such away that the uninitiated may gain sufficient background to use electrochemical methods
