'EXCESS HEAT' AND 'HEAT AFTER DEATH' IN A GAS-LOADING HYDROGEN/PALLADIUM SYSTEM

摘要

"Super-absorption" could occasionally appear when a H/Pd gas-loading system was heated by an incandescent tungsten filament. The system-pressure was kept on in 10~(-2) Pa for several hours without any aid of pumping. In this stage both "excess heat" and "heat after death" was observed once. By calibration, the feature constant of the system was 12.8℃/W in maximum. When the "excess heat" appeared, the system temperature was reached 153℃ at the highest whereas the stable inputting power was 0.45mW. When the "heat after death" appeared―there was no power input to the system―the temperature of the system abruptly jumped up to 761℃. In the former, 25kJ "excess heat" within 12 hours was measured which corresponded to 180 eV/atom Pd. And about 2MJ "heat after death" within 43 hours was corresponding to 13keV/atom Pd. The maximum excess powers in each case were 3.3 and 49W and the correlated power density were 230 and 3600 W/cm~3 Pd respectively. The variation results of concentration of Li-7and Li-6 and their abundance ratio in Pd suggested that the anomalous heat maybe come from a nuclear origin.
