— Evidence of a large heat excess produced in Ni-H systems and details of the calorimetric measurements are reported in this paper. Two cells which ran for long periods (about 300 days) produced an energy excess of 600 MJ and 900 MJ, respectively. PACS 25.70Ji – Fusion and fusion-fission reactions. 1. – Introduction In a previous paper  some of us… (More)
The results obtained in several experiments on Ni-H system are presented here. Photon emission during the preliminary phases of activation and 1 H isotope absorption are shown; their correlation with the kind of surfaces (Ni and its alloys) and with neutron and other particle emission in the excitation progress and in large heat production is also… (More)
We present a surface analysis of nickel alloy rods loaded with hydrogen. By comparing these with a blank (unused) metal rod, morphological differences and a different composition of the surface are observed. These surface modifications follow a spatial distribution along the rod. These results are compared with a previous analysis of similar samples.
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… (More)
This is an overview of our experimental activity during the last twelve years. We have been studying the Ni-H system at temperatures of about 700 K. Our investigations have revealed several interesting effects: a) energy production for long time b) neutron emission c) γ-ray emission d) charged particles emission e) appearance of elements other than Ni on… (More)
