本文研究了体心立方金属中与轻电子简单模型有关的小极化子扩散。通过超越的简化，这是经常介绍在研究电子小极化子输运，我们计算的扩散系数是合理的符合现有数据。特别是，从这些研究中出现的氢在体心立方金属中扩散观察到的“anoreous”同位素依赖性的解释。
The small-polaronic diffusion associated with simple models of light interstitials in bcc metals has been investigated. By transcending the simplifications which are often introduced in studying electronic small-polaron transport, we calculate diffusion coefficients which are reasonably consistent with available data. In particular, an explanation of the" anamalous" isotope dependence observed for hydrogen diffusion in bcc metals emerges from these studies.
