摘要：

Isotopic anomalies observed in meteorites for Ca, Ba, Nd and Xe are explained as due to the alteration of the isotopic ratios by a combined effect of mass fractionation, neutron-capture and cosmic-ray irradiation processes, which took place prior to and during the period of formation of the solar system. The neutron-capture process appears to have occurred at a temperature higher than that of the earth’s surface. © 1979, GEOCHEMICAL SOCIETY OF JAPAN. All rights reserved.
