X-RAY, HEAT EXCESS AND HE-4 IN THE D PD SYSTEM/

The energy balance between heat excess and He-4 in the gas phase has b een found to be reasonably satisfied even if the low levels of He-4 do not give the necessary confidence to state definitely that we are dea ling with the fusion of deuterons to give He-4. In the melted cathode, the data of which are reported, no He-4 was found at the achieved sen sitivity. X-ray film, positioned at 50 mm from the cell, roughly gave the image of the cathode through spots. Extended considerations have b een made to explain this evidence on the basis of the bundle nature of the cathode. From these considerations, the energy of the radiation a nd the total energy associated to it have been estimated, as 89 keV an d 12 kJ, respectively. This value is approximate to 0.5% of the energy measured by calorimetry in the same interval of time. The highest val ues of energy and excess power are 8.3 MJ and 10 W, respectively.
