This is the amount of the gas produced from 28.35 g of the unknown substance. Thus, 1 mol of gas is produced when 8.028 g of the substance reacts with water. Together with the flammability of the gas and the color of the flame, this leads us to conclude that the substance is lithium hydride:
LiH + H2O = LiOH + H2
On subsequent neutralization with HF, one would expect the formation of 7 g + 19 g = 26 g LiF from 8 g LiH, i.e. 3.25 times the original mass. But Holmes had only observed a 3.125-fold mass increase, i.e. only 25 g LiF had formed from 1 mol of LiH. This cannot be explained if all elements were present in their naturally occurring isotopic composition. The mass of 1 mol of LiF is, however, 25 g if it contains the pure stable isotope 6Li, which accounts for approximately 7 % of naturally occurring lithium (19F is the only stable isotope of fluorine). Since the molar mass of the substance is still 8 g/mol, it must be a compound of 6Li with deuterium. 6Li deuteride used

这是数额的天然气生产28.35克的不明物质。因此, 1摩尔的气体时产生8.028克的物质与水反应。加上可燃性气体和颜色的火焰,这使我们得出这样的结论:物质是氢化锂:
立+水+ =氢氧化锂氢
在随后的中高频,人们期望的形成7克+一九克=二六克氟化锂来自八克立,即3.25倍的原始质量。但霍姆斯只观察到3.125倍,质量提高,即只有25克氟化锂成立了1摩尔的立。这不能被解释如果所有的内容是在其自然发生的同位素组成。大众1摩尔的氟化锂然而, 25克,如果它含有纯净稳定同位素6Li ,占约7 %的自然发生的锂( 19F是唯一的稳定同位素的氟) 。由于摩尔质量的实质仍然是八克/摩尔,它必须是一个复合6Li与氘。 6Li使用氘是(和可能仍然是)主要的聚变燃料在热核武器。捕获后的中子产生的裂变连锁反应,下列程序进行:
