The first one is only 16 pages long. Do you mean Table 5 on p. 35 of the second paper? On p. 34, Miles speculates that the helium may be trapped in the cerium: We can estimate from Figure 18 that the Pd-Ce cathode produced 1.1 megajoules (MJ) of excess heat over a 110-day period. No chemical process can account for more than about 20 kJ in our system (Reference 4). Assuming typical deuteron fusion reactions that produce helium-4, the 1.1 MJ of excess enthalpy would produce a minimum of 3.7 × 10^17 atoms of helium-4 (Reference 22). Since no measurable helium was observed in the gas phase (Table 5), these helium atoms may remain in the Pd-Ce electrode. This would correspond to 1.4 × 10^14 atoms/milligram (mg) and would be readily measurable by Rockwell International (10^8 atoms/mg detection limit, see Reference 14). The measurement of 4He atoms within the Pd-Ce cathode has not been done. - Jed
