A table of energy levels based on the most accurate observations now available is given for the neutral He atom. The wavelengths contained in a revised list of He I lines from 320 A to 21132 A are also based on the best measurements, over half of them having been calculated from the wavenumber separations of appropriate levels. Several previously disturbing features of the He term scheme are obviated by the revised level values. In a discussion of the experimental results for this spectrum some comparisons with theory are made.
给出了基于目前可获得的最精确观测结果的中性氦原子能级表。从320埃到21132埃的He I谱线修订列表中包含的波长也基于最佳测量结果，其中一半以上是根据适当能级的波数间隔计算得出的。修订后的能级值消除了氦项方案中几个以前令人困扰的特征。在对该光谱的实验结果进行讨论时，与理论进行了一些比较。
