چکیده
Stark-induced amplitudes for the 6P1/2 − 7P1/2 transition in Tl I are calculated using the relativistic SD approximation in which single and double excitations of Dirac-Hartree-Fock levels are summed to all orders in perturbation theory. Our SD values αS = 368 a 3 0 and |βS |= 298 a 3 0 are in good agreement with the measurements αS=377(8) a 3 0 and βS = 313(8) a 3 0 by D. DeMille, D. Budker, and E. D. Commins [Phys. Rev. A50, 4657 (1994)]. Calculations of the Stark shifts in the 6P1/2 − 7P1/2 and 6P1/2 − 7S1/2 transitions are also carried out. The Stark shifts predicted by our calculations agree with the most accurate measured values within the experimental uncertainties for both transitions.

متن کاملMeasurement of the forbidden 6S - 8S M1 transition in caesium with an electric field
2014 The 6S1/2 8S1/2 caesium transition is excited in a Stark field, with a pulsed narrow-band nitrogenpumped dye-laser. It is detected by monitoring the fluorescence light emitted in the 8S1/2 6P1/2 decay. The scalarto-vector off-diagonal polarizability ratio is obtained : 03B1/03B2 = 4.8 ± 0.5. The M1 amplitude is observed through the electronic polarization created in 8S1/2 by its interferen...
متن کاملMeasurement of Linear Stark Interference in Hg
We present measurements of Stark interference in the 6S0 → 6P1 transition in Hg, a process whereby a static electric field E mixes magnetic dipole and electric quadrupole couplings into an electric dipole transition, leading to E-linear energy shifts similar to those produced by a permanent atomic electric dipole moment (EDM). The measured interference amplitude, aSI = (aM1 + aE2) = (5.8 ± 1.5)...

We consider evaluation of matrix elements with the coupled-cluster method. Such calculations formally involve infinite number of terms and we devise a method of partial summation sdressingd of the resulting series. Our formalism is built upon an expansion of the product C†C of cluster amplitudes C into a sum of n-body insertions. We consider two types of insertions: particle sholed line inserti...
متن کاملPhase transition of the dry friction between crystalline surfaces induced by normal load
A major source of energy dissipation and surface wear is the kinetic friction at the interfaces of sliding bodies. Traditionally, on a macroscopic scale, this undesirable effect is reduced with lubricating the surfaces by introducing oil into their interface. An interesting phenomenon, called superlubricity, has been reported on a nanometer scale where dry (without lubricant oil) fruition and w...
