摘要
中性原子的核与全剥0离电子的裸核在核衰变行为上将会出现A链上相邻两核素的正负β衰变的反置,从而修改了β稳定线.现代技术已有可能产生直到最重的铀裸核,并能存贮一定时间。这就可能对很重的类氢离子的S电子兰姆移位和它们的扭精细分劈值进行精确测量,从而检验量子电动力学(QED).简要介绍产生并存贮裸核的最新成就,在更高一级的水平上,将核物理与原子物理的研究结合起来。
In behaviour of nuclear disintegration a couple of nuclei linked by β+decay would be reversed by β-decay,when these nuclei are changed from neutral to nude state that results in the revision of β-stability line.With the nude nucleus β-decay into atomic bound states is noted by βb.By the modern technology it Is possible to produce up to Uranium nude nucleus which can be kept for a certain time.With the nude nuclei or H-like ions,the βb, theLamb shift on S-electron and the hyperfine splitting for very heavy H-like ions can be stud-ied. From the splitting accurate data the QED can be checke.In adition the achivevment of the technique of the cooling and storage heavy ion ring is briefly Introduced in the paper.The research of nuclear and atomic physics would be con-nected together in hlgher level.
