来自南极陨石Richardton的氙被发现在Xe/sup 129/中高度富集。这种同位素几乎肯定是由I/sup 129/的衰变形成的，而I/sup 129/作为一种天然放射性物质现已绝迹。据计算，（0.35 ± 0.06）x 10/sup 9/年之间的时间形成的元素和陨石。根据随后的计算，元素的年龄接近4.95 x 10/sup 9/年。（B.O.G.）
Xenon from the chondritic meteorite Richardton was found to be heavily enriched in Xe/sup 129/. This isotope almost centainly was formed from the decay of I/sup 129/, extinct at present as a natural radioactivity. It was calculated that (0.35 plus or minus 0.06) x 10/sup 9/ years elapsed between the time of formation of the elements and the meteorite. From subsequent calculations the age of the elements is placed at close to 4.95 x 10/sup 9/ years. (B.O.G.)
