在2.5 ~ 10 keV的能量范围内，测量了Ti，Fe，Pd，PdO和An中D（d，p）T反应中质子产额的激发函数。结果发现，在较低的能量反应速率变化很大的主体材料。最强烈的增强DD反应发生在PdO。在E-d = 2.5 keV时，它比裸氘核速率增强了五十倍，并且从激发函数推导出的屏蔽能达到600 eV。这种尺寸的增强不能单独用电子屏蔽来解释，但表明存在一种额外的和重要的固体屏蔽机制。
The excitation functions of the yield of protons emitted in the D(d,p)T reaction in Ti, Fe, Pd, PdO and An were measured for bombarding energies between 2.5 and 10 keV. It was found that the reaction rate at lower energies varies greatly with the host materials. The most strongly enhanced DD reaction occurs in PdO. At E-d = 2.5 keV, it is enhanced by factor of fifty from the bare deuteron rate and the screening energy deduced from the excitation function amounts to 600 eV. An enhancement of this size cannot be explained by electron screening alone but suggests the existence of an additional and important mechanism of the screening in solids.
