چکیده

The electric dipole polarizability of the lithium atom in the ground state is calculated including relativistic and quantum electrodynamics corrections. The obtained result αE = 164.074 0(5) a.u. is in a good agreement with the less accurate experimental value of 164.19(1.08) a.u. The small uncertainty of about 2ppm comes from the approximate treatment of quantum electrodynamics corrections. Our theoretical result can be considered as a benchmark for more general atomic structure methods and may serve as a reference value for the relative measurement of polarizabilities of the other alkali-metal atoms.

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives

The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

Hypertriton Electric Polarizability

A rigorous formalism for determining the electric dipole polarizability of a threehadron bound complex in the case that the system has only one bound (ground) state has been elaborated. On its basis, by applying a model wave function that takes into account specific features of the structure of the lightest hypernucleus and using the known low-energy experimental data for the p − n and Λ − d sy...
