Abstract

Neutron irradiation of gold foils in H₂O causes the release of ¹⁹⁸Au into the liquid in measurable quantities. Experiments prove that irradiation of the foils in water indeed yields 10 times more activity in the liquid than when the foil is removed from the liquid before irradiation. The activity of the gold foil shows no correlation with the yield of ejected ¹⁹⁸Au ions, but the duration of neutron irradiation does. However, not all experiments are fully conclusive as no linearity between irradiation duration and emitted ¹⁹⁸Au is apparent. A speciation experiment by crystallization reveals that the nuclear reaction produces ¹⁹⁸Au³⁺ ions quantitatively.

在类似于 Szilárd-Chalmers 的核反应中产生无载流子添加的 198Au3+ 水离子

中子辐照 H2O 中的金箔会导致 198Au 以可测量的数量释放到液体中。实验证明，在水中辐照金箔在液体中产生的活度比辐照前从液体中取出金箔时高出 10 倍。金箔的活性与射出的 198Au 离子的产量没有相关性，但中子辐照的持续时间却有相关性。然而，并非所有实验都能得出结论，因为辐照时间与发射的 198Au 之间并不存在明显的线性关系。通过结晶法进行的一项分型实验表明，核反应会产生定量的 198Au3+ 离子。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
