Evidence of electromagnetic radiation from Ni-H Systems

We report evidence of photon emission in three experiments with hydrogen loading of Ni slabs, during the degassing phase, when hydrogen was introduced into the cell, and during thermal cycling. In the first experiment we obtained excess power of about 20 W, while in the second experiment photon emission was observed instead of power production. In the third experiment, a Ni sample in hydrogen underwent thermal excitation and showed an increasing photon emission for a few hours.
