Title: Hydrogenlike Highly Charged Ions for Tests of the Time Independence of Fundamental Constants

Abstract

Hyperfine transitions in the electronic ground state of cold, trapped hydrogenlike highly charged ions have attractive features for use as frequency standards because the majority of systematic frequency shifts are smaller by orders of magnitude compared to many microwave and optical frequency standards. Frequency measurements of these transitions hold promise for significantly improved laboratory tests of local position invariance of the electron and quark masses.

  • A comparison of precision frequency measurements to quantum electrodynamics (QED) predictions for Rydberg states of hydrogenlike ions can yield information on values of fundamental constants and test theory. With the results of a calculation of a key QED contribution reported here, the uncertainty in the theory of the energy levels is reduced to a level where such a comparison can yield an improved value of the Rydberg constant.
  • A novel method is proposed for a laboratory test of the time independence of the fine-structure constant and of the electron to proton mass ratio, employing only electromagnetic resonators. For a resonator made out of a dielectric ionic or molecular crystal, the resonance frequencies depend on the product {alpha}{sup 2}m{sub e}/m{sub p} through the index of refraction. A test of the time independence of {alpha} and m{sub e}/m{sub p} can be performed by a search for a long-term change in the difference of two resonance frequencies exhibiting different dispersion. The method can be advantageously implemented with a single resonator. Themore » prospects of implementation using optical resonators, systematic effects, and experimental requirements for a test at the level of 4 x 10{sup -15}/yr relative variation in {alpha} or m{sub e}/m{sub p} are discussed. On the experimental side, birefringent monolithic sapphire optical resonators with high-reflectivity mirrors are fabricated and characterized. The measurements of optical materials with ultralow absorption loss (ppm/cm level), required for the proposed method, are also reported.« less
  • This paper discusses the prospects for production of an electron-polarized beam of multiply-charged ions by the technique of single-electron capture in a polarized atomic target. In addition, the authors suggest two atomic physics experiments which could utilize such beams. One of these is a test of the Standard Model of the Weak and Electromagnetic Interactions in a simple one-electron system. The other is a measurement of the hyperfine splitting of the ground state of a multiply-charged lithium-like system.
  • We report results from collinear time-dependent close-coupling (TDCC), distorted-wave (DW), and R matrix with pseudostates calculations for the electron-impact ionization of H-like ions up to Z=6 within an s-wave model. We compare the results of these calculations with those from a collinear classical trajectory Monte Carlo calculation to investigate the correspondence between the quantal and classical ionization probabilities as the principal quantum number of the initial state increases. In these model calculations, the electron-electron interaction is represented by the collinear s-wave potential given by 1/(r{sub 1}+r{sub 2}). We study the ionization probability from the ground state and highly excited statesmore » up to n=25 as a function of incident energy and the charge of the ion. We show that the fully quantal ionization probability converges to the classical results rapidly for hydrogen. The higher ion stages exhibit much slower convergence with respect to n. We observed good agreement between the DW and TDCC for the n range we have considered for B{sup 4+}. For hydrogen, we found fairly good agreement between the DW and TDCC for the ground state, but the worsening disagreement with increasing n. There is reasonable agreement between the results from the R-matrix calculations and the results from the TDCC calculations confirming the convergence of the TDCC results.« less
  • We report observations of nonequilibrium charge state distributions of slow, highly charged (33+{le} q{le}75+) ions after transmission of thin carbon foils. Charge equilibration times are determined directly from the dependencies of exit charge states on projectile velocity (0.5{times}10{sup 6}{lt}v{lt}10{sup 6} m/s) and foil thickness (5{endash}10thinspthinspnm). Ions like Xe{sup 44+} and Au{sup 68+} are found to equilibrate inside of solid matter in a time of only 7thinspthinspfs. {copyright} {ital 1999} {ital The American Physical Society}
