摘要
We propose an idea in spectroscopy to search for extra spatial dimensions as well as to detect the possible deviation from Newton＇s inverse-square law at small scale, and we take high-Z hydrogenic systems and muonic atoms as illustrations. The relevant experiments might help to explore a more than two extra dimensions scenario in the brane world model proposed by Arkani-Hamed, Dimopoulos, Dvali （ADD） and to set constraints for fundamental parameters such as the size of extra dimensions.
