UC Davis and Lawrence Berkeley National Laboratory Unveil Breakthrough in Low-Energy Nuclear Fusion
Scientists at UC Davis and Lawrence Berkeley National Laboratory have made a significant discovery in nuclear fusion research. They found that surrounding materials can dramatically increase the frequency of nuclear fusion at low energies, a development that opens a new research area called materials-driven fusion. The team conducted experiments by packing deuterium, a heavy form of hydrogen, into thin metal foils made of titanium and palladium. By firing a beam of deuterium ions at these foils, they observed that fusion occurred about a quintillion times more often than in reactions without a host material. This unexpected result challenges standard physics theory, which predicts a sharp drop in fusion rates at lower energies. The findings suggest that the subatomic structure of host metals, including electrons and tiny defects, may shield repulsive forces between deuterium nuclei, facilitating fusion.
