Title: Magic-wave-induced {sup 1}S{sub 0}-{sup 3}P{sub 0} transition in even isotopes of alkaline-earth-metal-like atoms

Abstract

The circular polarized laser beam of the 'magic' wavelength may be used for mixing the {sup 3}P{sub 1} state into the long-living metastable state {sup 3}P{sub 0}, thus enabling the strictly forbidden {sup 1}S{sub 0}-{sup 3}P{sub 0} 'clock' transition in even isotopes of alkaline-earth-metal-like atoms, without a change of the transition frequency. In odd isotopes the laser beam may adjust to an optimum value the linewidth of the clock transition, originally enabled by the hyperfine mixing. We present a detailed analysis of various factors influencing resolution and uncertainty for an optical frequency standard based on atoms exposed simultaneously to the lattice standing wave and an additional 'state-mixing' wave, including estimations of the 'magic' wavelengths, Rabi frequencies for the clock and state-mixing transitions, ac Stark shifts for the ground and metastable states of divalent atoms.

  • We have observed the 1{ital s}2{ital s}{sup 1}{ital S}{sub 0}-1{ital s}2{ital p}{sup 3}{ital P}{sub 0} transition in {sup 14}N{sup 5+} using Doppler-tuned fast-beam laser spectroscopy. This transition, absolutely forbidden for atoms with zero nuclear spin, occurs due to mixing of states of different {ital J} by the hyperfine interaction. By measuring the difference between the 2{sup 1}{ital S}{sub 0}-2{sup 3}{ital P}{sub 1,{ital F}} and 2{sup 1}{ital S}{sub 0}-2{sup 3}{ital P}{sub 0} transition energies, we have obtained a value for the 1{ital s}2{ital p}{sup 3}{ital P}{sub 1}-2{sup 3}{ital P}{sub 0} fine-structure splitting in N{sup 5+}. Our result will test quantum-electrodynamic correctionsmore » to recent high precision calculations [Z.-C. Yan and G.W.F. Drake, Phys. Rev.

  • Accurate [ital ab] [ital initio] multiconfigurational-Dirac-Fock (MCDF) calculations of the lifetimes of the spin-forbidden 2[ital s][sup 2] [sup 1][ital S][sub 0]--2[ital s]2[ital p] [sup 3][ital P][sub 1] transition and the allowed 2[ital s][sup 2] [sup 1][ital S][sub 0]--2[ital s]2[ital p] [sup 1][ital P][sub 1] transition in Be-like ions have been performed. The importance of the inclusion of the Breit interaction to obtain accurate fine-structure splittings and mixing coefficients is discussed and the noted discrepancy between the length and velocity gauges for the intercombination line in the lighter ions is addressed. Different optimization procedures are evaluated. For C III the experimentalmore » intercombination transition rate has been measured to be 121.9 s[sup [minus]1] with an accuracy of 6%. The current calculation gives 100.3[plus minus]4 s[sup [minus]1], in agreement with other recent calculations.« less
  • We report calculations assessing the ultimate precision of an atomic clock based on the 578 nm 6 {sup 1}S{sub 0}{yields}6 {sup 3}P{sub 0} transition in Yb atoms confined in an optical lattice trap. We find that this transition has a natural linewidth less than 10 mHz in the odd Yb isotopes, caused by hyperfine coupling. The shift in this transition due to the trapping light acting through the lowest order ac polarizability is found to become zero at the magic trap wavelength of about 752 nm. The effects of Rayleigh scattering, multipole polarizabilities, vector polarizability, and hyperfine induced electronic magneticmore » moments can all be held below 1 mHz (about one part in 10{sup 18}). In the case of the hyperpolarizability, however, larger shifts due to nearly resonant terms cannot be ruled out without an accurate measurement of the magic wavelength.« less
  • The spectral dependences of the isotopic selectivity of the optical excitation of zinc atoms in the course of an efficient photochemical reaction with molecules of a reagent gas are calculated within the framework of a simple model taking into account the gas mixture flow. At a certain frequency detuning of monochromatic laser radiation, a high selectivity of isotope separation is realized at the end of the interaction region under the condition that the isotopic shifts are smaller than the Doppler broadening.
  • We report direct laser spectroscopy of the {sup 1}S{sub 0}-{sup 3}P{sub 0} transition at 265.6 nm in fermionic isotopes of neutral mercury in a magneto-optical trap. Measurements of the frequency against the LNE-SYRTE primary reference using an optical frequency comb yield 1 128 575 290 808.4{+-}5.6 kHz in {sup 199}Hg and 1 128 569 561 139.6{+-}5.3 kHz in {sup 201}Hg. The uncertainty, allowed by the observation of the Doppler-free recoil doublet, is 4 orders of magnitude lower than previous indirect determinations. Mercury is a promising candidate for future optical lattice clocks due to its low sensitivity to blackbody radiation.
