The Metal Around Fusion Is Not a Passive Wall
Deuterium-loaded foils produced an unexpected low-energy reaction plateau, opening a route to study materials-driven fusion.
Summary
Deuterium-loaded foils produced an unexpected low-energy reaction plateau, opening a route to study materials-driven fusion.
UC Davis and Berkeley Lab researchers fired deuterium ions into palladium and titanium foils prepared by different loading methods. Below 2.5 kiloelectronvolts, some samples showed fusion rates vastly above the bare-reaction expectation, forming an unexpected plateau that depended on the material environment. Electrons and defects may partly screen repulsion, but the mechanism is unresolved. The experiment concerns low-energy reaction physics and possible neutron sources, not a demonstrated power reactor.
