中子存在的实验证据进一步支持了原子核可能由质子、中子和δ粒子组成的观点。Heisenberg2最近发现，使用只有质子和中子作为基石的模型很方便。在不同的论文中，Aston3已经确定了许多化学元素的同位素组成，但从稳定性的考虑，还不可能说可能会出现什么同位素。本说明的目的是指出低质量元素的规律性，并为此类元素提出一种可能的建立原则。
THE experimental evidence for the existence of the neutron has given added support to the view1that the nucleus may be composed of protons, neutrons, and δ-particles. Heisenberg2has recently found it convenient to use a model with protons and neutrons only as the building-stones. In various papers, Aston3has determined the isotopic constitution of many of the chemical elements, but it has not been possible to say, from considerations of stability, just what isotopes may be expected to occur. The purpose of this note is to point out regularities for elements of low mass, and to suggest a possible building-up principle for such elements.
