14MeV中子引起^(133)Cs(n,α)反应所形成的^(130)Ⅰ的氧化价态分布

THE DISTRIBUTION OF OXIDATION STATES OF ^(130)T FORMED IN ^(133)Cs(n, a) REACTION INDUCED BY 14MeV NEUTRONS

本文研究了14MeV中子引起^(133)Cs(n,α)反应所形成的^(130)Ⅰ热原子的化学行为。用萃取法分离还原态(Ⅰ-+Ⅰ°),用强碱性阴离子交换柱分离IO_3^-和IO_4^-。结果表明,在固体中核反应直接形成的反冲原子趋于还原态。

The Chemical behavior of 130I hot atoms formed in 133Cs(n,α) reaction induced by 14MeV neutrons has been studied. The reduced states (I-+I°) are separated by extraction, and IO3- and IO4- forms are isolated by strong-base anionic exchange column. Results show that the recoiling atoms formed by nuclear reaction prefer reduced states in solid matrixes.
