Siena - Ita/y (3) Fiat Avio, Colleferro - Italy Abstract We repor~ the rcsuj~ obtained in ~hre diffi rent laboratories on the i-h sys~em during several year!! of experimen~. Hea.t production was observed In different cells for long periods, with a maximum power of 70 W. In several occa.- ions we detected gamma ray emission and in one case also a neutron emission. The analysis or iekel samples which loaded Hydrogen gas showed the existence ofother elements not present in the original specimens. Finally, we present tracks detected in a diffusion chamher of ionising particles from a specimed which produced heat. 1 Introduction The observation by one of the a.uthors (F. Piantelli) of an anomalous behaviour of the system Ni S was the starting point of a systematic research 00 t.l;lese effec [11. Different cells and specimens were built and put into operation in order to study the characteristics of the phenomenon. For a detailed description of the cells, th reader is referred to [2J [3J. Nickel specimens or specimens of other nickel plated materials were put into our cells and treated at various temperatures and hydrogen pressures in order to obtain a high level of H.loading. In some cases a relevant absorption was obtained, while other specimens. even if treated in a similar manner, absorbed much less. Typical values of pressure and temperature employed in the loading operations were in the 200+ WOO mbar and K range. The use of subatmospheric pressures guarantees that the observed pressure decreases were due to Hydrogen absorption a.nd not to cell leakage. During the treatments for loading Hydrogen or as a consequence of Hydrogeo absorption, a series of different phenomena, which will described in tile following, were observed. 69
