在实验研究了5种氘注入固体靶（C，Al，Zr，Pd，Ta）的H-2（d，p）H-3反应中电子屏蔽效应的基础上，采用改进的介电函数理论进行了理论计算。该理论正确地描述了所观察到的靶材料的筛选能量的依赖性，低估，但是，约2倍的绝对值。应用有效屏蔽能方法，计算了理论截面、厚靶产额以及核反应速率，直至对应于所谓的冷聚变实验条件的能量。这允许在更高能量下的实验结果与在重水电解实验中实现的那些进行比较。
Based on our experimental studies of the electron screening effect in the H-2(d, p) H-3 reaction for five deuteron- implanted solid targets ( C, Al, Zr, Pd, Ta), theoretical calculations have been performed within an improved dielectric function theory. The theory describes correctly the observed target material dependence of the screening energies, underestimating, however, the absolute values by about a factor of 2. Applying an effective screening energy approach, the theoretical cross- sections, thick- target yields as well as nuclear reaction rates have been calculated down to the energies corresponding to the conditions of so- called cold- fusion experiments. This allows for a comparison of the experimental results at higher energies with those achieved in the heavy- water electrolysis experiments.
