Experimental evidence of cold nuclear fusion in a measurement under the Gran Sasso Massif

We have observed the emission of 2.5 MeV neutrons following the electrolytic infusion of deuterons into titanium electrodes. The present results were obtained by n-ψ discriminating proton-recoil detectors at the Gran Sasso Laboratory. The observed neutron emission rate is comparable in size to the one recently reported by Jones and coll.
