Physical Review A

Comments on the hyperfine structure of the 4D2 state of rubidium

Abstract

In a recent paper Lee, Rodgers, Das, and Sternheimer have reported on the evaluation of the fine and hyperfine structure of the $4^{2}D$ state of the rubidium atom by considering the first-order polarization of the electron core. By means of more extensive calculations we have shown that the first-order results can be quite unreliable for such strongly perturbed systems. By including polarization effects to all orders and the most important correlation effects, we have been able to reproduce the experimental results for this state quite well. The good agreement obtained by Lee et al. for the spin-dipole parameter is in our opinion largely fortuitous.

Cascade Anticrossing Measurement of the Anomalous Hyperfine Structure of the 4D2 State of Rubidium

K. H. Liao, L. K. Lam, R. Gupta +1 more

A new technique, cascade anticrossing spectroscopy, has been developed to determine the effective values of $〈{r}^{\ensuremath{-}3}〉$ for the spin-dipole, orbital, contact, and quadrupole hyperfine interaction terms for the $4^{2}D$ state of Rb. They are, in units of ${10}^{24}$ ${\mathrm{cm}}^{\ensuremath{-}3}$, ${〈{r}^{\ensuremath{-}3}〉}_{d}=\ensuremath{-}0.36(8)$, ${〈{r}^{\ensuremath{-}3}〉}_{l}=+0.20(2)$, ${〈{r}^{\ensuremath{-}3}〉}_{c}=\ensuremath{-}4.3(1)$, and ${〈{r}^{\ensuremath{-}3}〉}_{q}=+0.79(66)$, respectively. The negative value of ${〈{r}^{\ensuremath{-}3}〉}_{d}$ and the unexpectedly large value of ${〈{r}^{\ensuremath{-}3}〉}_{c}$ are surprising. The fine-structure splitting has been measured to be - 13 360.9(8) MHz.

Polarization spectroscopy of rubidium atoms: Theory and experiment

Huy Diep, Geol Moon, Heung‐Ryoul Noh

We present a theoretical and experimental study of polarization spectroscopy of rubidium atoms. All of the populations of the magnetic sublevels were calculated from the rate equations and used in the calculation of the polarization spectroscopy spectra. Using this model, we could generate theoretical line shapes of the polarization spectra on the ${D}_{2}$ transitions of rubidium atoms. The experimental results demonstrated that our model accurately reproduced spectra for all transitions in hyperfine structures.

Hyperfine Interaction, Zeeman and Stark Effects for Excited States in Rubidium

G Belin, Lennarth Holmgren, Sune R. Svanberg

Highly excitedPandDstates in87Rb were examined using a two-step excitation procedure. A conventional rf lamp and a CW dye laser were used for the first and second step, respectively. The following results for the magnetic dipole interaction constanta, the electric quadrupole interaction constantb, the LandégJfactor, and the tensor polarizability α2were obtained in level-crossing and optical-double-resonance experiments: 92P3/2:a= 4.05(3) MHz,b=0.55(3) MHz,gJ= 1.3335(15) 102P3/2:a= 2.60(8) MHz,gJ= 1.3332(20) 82D3/2:a= 2.840(15) MHz,b= 0.17(2) MHz 82D5/2:a= -1.20(15) MHz,gJ= 1.1998(15) 92D3/2:a= 1.900(10) MHz,b= 0.11(3) MHz 92D5/2:a= (-)0.80(15) MHz,gJ= 1.1995(15), α2= 180.3(9.0) MHz/(kV/cm)2 Many-body calculations of the hyperfine structure of Rb have been performed. The polarization effect is included to all orders, whereas the correlation effect is omitted. The negativeafactors for the2D5/2states, indicating large perturbations, are explained by the polarization contribution. A review of experimental hyperfine interaction constants, LandégJfactors and tensor polarizabilities for rubidium is given together with theoretical values of theafactors. The quadrupole moment for87Rb is obtained from thebfactors for the2P3/2and2D3/2states, using quadrupole parameters from the many-body calculations. The correlation effect is included in a semi-empirical way.

Cascade Radio-Frequency Spectroscopy of Excited S and D States of Rubidium; Anomalous D -State Hyperfine Structure

R. Gupta, Sharon Chang, C. Tai +1 more

We report the first successful measurements by cascade radio-frequency spectroscopy of the hyperfine structures of excited $S$ and $D$ states of rubidium. We obtain the following magnetic dipole coupling constants (in MHz): for ${\mathrm{Rb}}^{87}$, $A(7^{2}S_{\frac{1}{2}})=312.5\ifmmode\pm\else\textpm\fi{}3.5$, $A(5^{2}D_{\frac{3}{2}})=14.1\ifmmode\pm\else\textpm\fi{}0.5$, $A(5^{2}D_{\frac{5}{2}})=\ensuremath{-}8.0\ifmmode\pm\else\textpm\fi{}1.5$; for ${\mathrm{Rb}}^{85}$, $A(7^{2}S_{\frac{1}{2}})=92.6\ifmmode\pm\else\textpm\fi{}1.0$, $A(5^{2}D_{\frac{3}{2}})=4.1\ifmmode\pm\else\textpm\fi{}0.5$. The anomalous, negative value of $A$ for the $5^{2}D_{\frac{5}{2}}$ state may be related to the anomalously small fine-structure interval of the $5D$ state of rubidium.

Optical spectroscopy of the 5 p 3/2 → 6 p 1/2 electric dipole-forbidden transition in atomic rubidium

F. Ponciano-Ojeda, C Mojica-Casique, Santiago Hernández-Gómez +7 more

Abstract We present the first evidence of excitation of the 5 p 3 / 2 → 6 p 1 / 2 electric dipole-forbidden transition in atomic rubidium. The experiments were done in a rubidium vapor cell using Doppler-free optical–optical double resonance spectroscopy with counter-propagating beams, with a similar scheme to the excitation of the other fine transition 6 p 3/2 in the 6 p J manifold reported in Ponciano-Ojeda et al (2015 Phys. Rev. A 92 042511). The 5 p 3 / 2 → 6 p 1 / 2 dipole-forbidden excitation occurs at a wavelength λ ≈ 917.5 nm. The spectra showed the two main hyperfine states of the 6 p 1/2 manifold, and also resolved up to three satellites that appear due to effects of selection of velocities in thermal rubidium atoms. The polarization dependence of the relative intensities of the hyperfine lines of the decay fluorescence is also investigated. The data show that the individual line intensities and also the total cross-section have a strong dependence on the polarization direction. Experimental data for different polarization configurations of the light beams used in this two-photon spectroscopy are compared with the results of calculations that consider a strong atom-field coupling in the preparation step, followed by a weak electric quadrupole excitation and the blue fluorescence decay emission. Good agreement between experiment and this three-step model is found in the case of linear–linear polarizations, which confirms the results found for the 5 p 3 / 2 → 6 p 3 / 2 forbidden transition. The results presented here complete the information about the 5 p 3/2 → 6 p J electric dipole-forbidden transition in rubidium.

Coupled rearrangement channel calculation of the fine and hyperfine structures of the antiprotonic helium atom

Nobuhiro Yamanaka, Yasushi Kino, Hiroshi Kudo +1 more

We precisely calculate the fine and hyperfine structure splittings of the $(v,J)=(1,35)$ state in the antiprotonic helium atom, where $v$ is the vibrational quantum number and $J$ is the total orbital angular momentum. The coupled rearrangement channel method is employed to efficiently describe correlation effects in the three-body system with atomic and molecular characters. An accuracy of better than ${\ensuremath{\alpha}}^{2}\ensuremath{\approx}50\mathrm{ppm}$ has been achieved. The result obtained is in good agreement with the previous calculation within $\ensuremath{\sim}200 \mathrm{ppm}.$ We also examine the correlation effects, in particular orbital polarization effects.
