Cold fusion rates in titanium foils

Abstract A new, very sensitive test (10 -12 W cm -3 ) of cold fusion in titanium charged by deuterium has been carried out. The penetration of deuterium into titanium foils, in the presence of metallic salts (like in the experiments of Jones et al.), has been carefully checked and found to be very inefficient; the quoted fusion rates are thus correspondingly larger by orders of magnitude. Experiments in different experimental conditions in which the deuterium penetration was under control have been performed. So far no cold fusion event has been found.
