摘要

研究了二氯化锆二茂和二氯化钼二茂金属原子中(n - γ)中子俘获反应产生的放射性物质的性质和分布。Zr-95、Zr-97和Mo-99的保留率分别为20.22%、12.63%和20.23%。二氯化95zr -锆二茂和99mo -钼二茂中的β-转变导致大约80%的子晶Nb-95和Tc-99m保持与母体相同的分子形态。

Recoil phenomena in zirconocene and molybdocene dichlorides and radiochemical synthesis via subsequent beta-transformations

The nature and distribution of radioactive species resulting from (nγ) neutron-capture reactions in the metal atoms of zirconocene dichloride and molybdocene dichloride were investigated. Retention values of 20.22, 12.63 and 20.23% were obtained for Zr-95, Zr-97 and Mo-99 respectively. β-Transformation in ⁹⁵Zr-zirconocene dichloride and ⁹⁹Mo-molybdocene dichloride led to approximately 80% of the respective daughters Nb-95 and Tc-99m being retained at the same molecular form as the parent.
