Second-order effects on the hyperfine structure of P states of alkali-metal atoms
نویسندگان
چکیده
We analyze second-order M1-M1 and M1-E2 effects on the hyperfine structure HFS of the lowest-energy P states of alkali-metal atoms arising from the coupling of the two J=1 /2,3 /2 fine-structure levels through the hyperfine interaction. We find these effects to be especially sizable in Li, leading to a 9 correction to the most accurate reported experimental value of the A P1/2 HFS constant of Li Das and Natarajan, J. Phys. B 41, 035001 2008 . For the remaining alkali-metal systems, the results tabulated within may be referenced as higher precision is sought in experimental determination of the HFS constants.

Calixarenes are a readily available and important class of macrocycles in supramolecularchemistry. Calixarenes have generated considerable interest due to their basket shaped structureand as useful building blocks to synthesize selective receptors for the guest species, notably alkali,alkaline earth, lanthanide and transition metal cations. In this work studied on the complexingproperties of a ...

Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements and static polarizabilities for alkali-metal atoms. Abstract Removal energies and hyperfine constants of the lowest four ns, np 1/2 and np 3/2 states in Na, K, Rb and Cs are calculated; removal energies of the n=7–10 states and hyperfine constants of the n=7 and 8 states in Fr are also cal...

The infinite-order regular approximation (IORA) and IORA with modified metric (IORAmm) is used to develop an algorithm for calculating relativistically corrected isotropic hyperfine structure (HFS) constants. The new method is applied to the calculation of alkali atoms Li-Fr, coinage metal atoms Cu, Ag, and Au, the Hg(+) radical ion, and the mercury containing radicals HgH, HgCH(3), HgCN, and H...
متن کاملStimulated Raman transitions via multiple atomic levels
We consider the stimulated Raman transition between two long-lived states via multiple intermediate states, such as between hyperfine ground states in the alkali-metal atoms. We present a concise treatment of the general, multilevel, off-resonant case, and we show how the lightshift emerges naturally in this approach. We illustrate our results by application to alkali-metal atoms and we make sp...

We present a method for robust timekeeping in which alkali-metal atoms are interrogated in a Ramsey sequence based on stimulated Raman transitions with optical photons. To suppress systematic effects introduced by differential ac Stark shifts and optical intensity gradients, we employ atom optics derived from Raman adiabatic rapid passage (ARP). Raman ARP drives coherent transfer between the al...
