- Abstract
The hyperfine structure of the ground 2 S-states of the three-electron atoms and ions is investigated. By using our recent numerical values for the doublet electron density at the atomic nucleus, we determine the hyperfine structure of the ground (doublet) 2 S-state(s) in the Li and Li atoms. Our predicted values (228.2058 and 803.5581 MHz, respectively) agree well with the experimental values 228.20528(8) MHz (Li) and 803.50404(48) MHz (Li [R.G. Schlecht and D.W. McColm, Phys. Rev. 142, 11 (1966)]). The hyperfine structures of a number of lithium isotopes with short lifetimes, including Li, Li, and Li atoms are also predicted. The same method is used to obtain the hyperfine structures of the three-electron Be and Be ions in their ground 2 S-states. Finally, we conclude that our approach can be generalized to describe the hyperfine structure in the triplet n S-states of the four-electron atoms and ions.
