【摘要】 <正> 我们用14MeV中子引起¹³³Cs（n,α）反应所形成的¹³⁰I热原子的氧化价态分布来研究核反应直接形成的热原子碘的状态。首先用¹³¹I合成¹³¹I^-,¹³¹I⁰,¹³¹IO₃^-等标记化合物,详细测定了各价态之间的同位素交换。结果表明除了I₂⁰-I-之间外,各价态之间在20±50℃、30-更多还原

【Abstract】 The results show that the influence of the matrix on the percentage distribution of IO- 4 is small; the oxidation states of 130I found in the cesium chloride are mostly reduction states; the appearance in reduction state for the recoiling atoms formed directly by nuclear reaction is a general phenomenon; the decrease of reduced state in the cesium nitrate matrix is because of oxidation of NO- 2 produced by the irradiation decomposition of nitrate and an obvious unisolated unknown iodine compound.更多还原
