太阳风中稀有气体的同位素组成显示出轻同位素的高度富集。当对所有五种惰性气体的质量分馏进行校正时，可以根据行星固体中已确定的两种原始惰性气体组分来解决。分配分馏的太阳过程，选择性地丰富在太阳表面的轻原子核的原因。当太阳表面的元素丰度被校正为这种分馏时，它表明太阳体中主要元素的原子丰度是（按降序排列）：Fe，Ni，O，Si，S和Mg。在大约1%原子丰度水平的太阳能元素包括He、C、Ne、Ca和Cr。这些结果表明，氢聚变可能不是太阳的主要能源。
The isotopic compositions of noble gases in the solar wind show high enrichments of light isotopes. When corrected for mass fractionation all five noble gases there can be resolved in terms of the two primitive noble gas components that have been identified in planetary solids. Reasons are presented for assigning the fractionation to a solar process that selectively enriches lighter nuclei at the surface of the Sun. When abundances of the elements at the Sun's surface are corrected for this fractionation, it is shown that atomic abundances for major elements in the bulk Sun are (in decreasing order): Fe, Ni, O, Si, S and Mg. Solar elements at about the 1% atomic abundance level include He, C, Ne, Ca and Cr. These results suggest that fusion of hydrogen is probably not the Sun's primary energy source.
