我们建议使用双原子分子离子来寻找基本常数变化的强烈增强效应。相对增强发生在不同性质的近简并能级之间的跃迁。由于分子离子的捕获技术已经发展起来,分子HBr$^+$,HI$^+$,Br$^+_2$,I$^+_2 $,IBr$^+$,ICl$^+$和IF$^+$是非常有希望的候选者,用于这种未来的研究。
We propose to use diatomic molecular ions to search for strongly enhanced effects of variation of fundamental constants. The relative enhancement occurs in transitions between nearly degenerate levels of different nature. Since the trapping techniques for molecular ions have already been developed, the molecules HBr$^+$, HI$^+$, Br$^+_2$, I$^+_2$, IBr$^+$, ICl$^+$, and IF$^+$ are very promising candidates for such future studies.
