摘要：
Titanium isotopic ratios in some terrestrial and meteoritic materials have been measured. Most have the same ratios within the experimental precisions. Some inclusion materials from the Allende meteorite have a statistically significant enhancement of the order of 1‰ in the 50/49 ratio, probably due to a nucleogenic anomaly in 50Ti abundance. © 1979 Nature Publishing Group.
