Research Abstract

The variable types of neutron capture reactions under the variable environmental conditions were found from the isotopic results of lunar surface materials, martian meteorites, gas-rich meteorites, stony meteorites having long cosmic-ray exposure ages, stony-iron meteorites, and the Oklo natural reactor samples. The quantitative characterization of the neutron capture reactions were performed from the isotopic shifts of^<150> Sm/^<149> Sm,^<156> Gd/^<155> Gd, and^<158> Gd/^<157> Gd in individual samples because of the large neutron capture cross sections of^<149> Sm,^<155> Gd and^<157> Gd.
