使用来自 30、100 和 450 kV 加速器的强束流并结合近距和远距几何形状的探测器，在质心能量 E=1.6 至 130 keV 下研究了 d(d, n)3He 和 d(d,p) 聚变反应。截面比 R(E)=σ(d,n)/σ(d, p) 在低能量下接近一致（2%以内）；因此，没有实验证据证明亚库仑能量下的奥本海默-菲利普斯效应。 E≤10keV时d(d，p)t的横截面显示了电子屏蔽效应的清晰证据。然而，观察到的横截面增强明显大于可用原子物理模型所能解释的。
Thed(d, n)3He andd(d,p)tfusion reactions have been studied at center-of-mass energies E=1.6 to 130 keV using intense beam currents from 30, 100, and 450 kV accelerators in combination with detectors in close and far geometry. The cross sesction ratio,R(E)=σ(d,n)/σ(d, p), approaches unity (within 2%) at low energies; thus there is no experimental evidence for the Oppenheimer-Phillips effect at subcoulomb energies. The cross sections of d(d, p)t at E≦10keV show clear evidence for electron screening effects. However, the observed cross section enhancement is significantly larger than can be accounted for from available atomic physics models.
