金属中でのD+D核融合反応が,クーロン障壁よりはるかに低いkeVエネルギー領域まで測定された.その結果,反応率がホスト金属に大きく依存すること,さらに,ある種の金属中では,反応率が常識では説明できないほど大きく増大することが明白になった.Li+D反応でも反応率の異常増大が観測され,金属中の核融合反応では,既知の遮蔽効果に加え,反応率大幅増大を可能にする重要なメカニズムの存在が強く示唆されている.
The D+D fusion reactions in metals were measured with bombarding energies down to kcV, far below the Coulomb barrier. It was shown that the reaction rate depends on the host metals very much ; in some metals observed were unexpectedly large enhancement of the reaction rate. Similar enhancement was seen for the Li+D reaction in metal. The observed enhancement cannot be explained by the known screening mechanism alone but suggests the existence of an additional and important mechanism to enhance the reaction rate in metals.
