Abstract

The magnetic resonance between the Zeeman sublevels in the lower excited states 6 2 P 3/2 and 7 2 P 3/2 of 133 Cs atom has been observed in a medium magnetic field (15∼160 Gauss) by use of optical double resonance technique. From the positions of the resonance signals, the hyperfine coupling constants A , B , and the quadrupole moment Q have been evaluated as follows: A (6 2 P 3/2 )=50.45 MHz, B (6 2 P 3/2 )=-0.60 MHz, A (7 2 P 3/2 )=16.55 MHz, B (7 2 P 3/2 )=-0.20 MHz, and Q =-0.0045×10 -24 cm 2 . The effects of the collisions with noble gas atoms (He, Ne, and Ar) on the resonance signals have been observed. For the resonance signals between the Zeeman sublevels | F =3, m F =-2>↔|3, -3> in 6 2 P 3/2 state, |4, -3>↔|4, -4>, |4, -2>↔|4, -3>, |5, -4>↔|5, -5>, and |5, -2>↔|5, -3> in 7 2 P 3/2 state, the crosssections of the collisional broadening have been evaluated from variations of the line widths.

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.

mJ Mixing in Oriented 6P122 Cesium Atoms, Induced in Collisions with Noble Gases

J. Guiry, L. Krause

The cross sections for disorientation of magnetically oriented $6^{2}P_{\frac{1}{2}}$ cesium atoms, induced in collisions with noble gases, have been determined using Zeeman-scanning techniques at kilogauss magnetic fields. The ${m}_{J}=\ensuremath{-}\frac{1}{2}$, ${m}_{I}=\ensuremath{-}\frac{7}{2}$ hyperfine Zeeman substate was populated selectively by irradiating the cesium-vapor-noble-gas mixture with cesium-resonance radiation, and collisional transitions to the ${m}_{J}=+\frac{1}{2}$, ${m}_{I}=\ensuremath{-}\frac{7}{2}$ substate were monitored by measurements of the relative intensities of the ${\ensuremath{\sigma}}^{\ensuremath{-}}$ and ${\ensuremath{\sigma}}^{+}$ components in resonance fluorescence observed in the direction parallel to the magnetic field. The following cross sections were obtained: Cs-He, 11.8 ${\mathrm{\AA{}}}^{2}$; Cs-Ne, 4.7 ${\mathrm{\AA{}}}^{2}$; Cs-Ar, 10.7 ${\mathrm{\AA{}}}^{2}$; Cs-Kr, 37.9 ${\mathrm{\AA{}}}^{2}$; Cs-Xe, 71.7 ${\mathrm{\AA{}}}^{2}$.

Zeeman mixing in 6(2)P rubidium atoms induced in noble-gas collisions.

Richard B. Middleton

Rubidium vapour, together with a noble gas contained in a cell located in a 4.75T magnetic field, was irradiated with light from a pulsed dye laser. This radiation produced selective excitation of the 6$\\sp{\\rm z}$P$\\sb{\\rm J,m}$ (J = 1/2, 3/2, m = $-$3/2, $-$1/2, 1/2, 3/2) Zeeman substates. Collisions of the excited 6P atoms with He, Ne and Ar atoms and the resulting Zeeman mixing produced a population in the whole 6P Zeeman manifold and resulted in the emission of a Zeeman fluorescence spectrum which was resolved with a scanning Fabry-Perot interferometer, detected with a photomultiplier and stored in a multichannel scaler. The analysis of the fluorescence intensities of the components emitted in the decay of the directly (optically) excited state and of the collisionally populated states in relation to the noble gas densities, yielded the Zeeman mixing cross sections and the cross sections for the relaxation of dipole, quadrupole, and octupole moments.Dept. of Physics.

Optical Methods of Atomic Orientation and of Magnetic Resonance*

Alfred Kastler

In the optical excitation of atoms with polarized light, producing excited atoms, only some of the Zeeman sublevels of the excited state are actually reached, so that large differences of population can be built up between Zeeman sublevels or between hyperfine structure (hfs) levels. This property can be used to detect radio-frequency resonance in optically excited atomic states. These resonances produce a characteristic change in intensity or in the degree of polarization of the light re-emitted. Zeeman intervals, Stark effects, and hfs intervals can be measured in this manner. (The Stark constant of the 63P1 level of Hg and the electric quadrupole moments of the alkali atoms have been obtained in this way.)The technique of “optical pumping” gives a way to concentrate atoms in some of the Zeeman sublevels of one of the hfs levels of the ground state.Atomic orientation has been obtained with the Na atom, in an atomic beam and in the vapor in equilibrium with the metal. The orientation effects have been studied by detection of radio-frequency resonance signals in the ground state. Orientation can be increased many times by adding a variable pressure of a foreign gas to the pure Na vapor. Because of the coupling between nuclear spin and electron spin, nuclear orientation is produced at the same time as atomic orientation.

Magnetic-field decoupling of an alkali-metal excited-state hyperfine structure

William Arie van Wijngaarden, J. Sagle

The theory of how excited-state hyperfine structure can be determined using a magnetic field to decouple the nuclear and electronic angular momentum is presented. The initial excited state is assumed to have an anisotropic Zeeman sublevel population distribution, which can be conveniently created by a laser-induced multiphoton excitation of an unpolarized atom. The Zeeman sublevel populations are subsequently mixed by the hyperfine interaction. The degree of mixing is controlled by a magnetic field applied along the quantization axis. The relative Zeeman sublevel populations can be monitored by detecting the polarization of fluorescence emitted when the excited state radiatively decays. It is convenient to take the ratio of two time-integrated fluorescent signals measured for orthogonal linear polarizations, since this is independent of the excited-state number density. The plot of this ratio versus magnetic field is very well approximated by a Lorentzian curve whose half-width is proportional to the magnetic dipole hyperfine coupling constant. This method was used to determine the magnitude of the magnetic dipole constant of the cesium 8${\mathit{D}}_{3/2}$ state to be 3.92\ifmmode\pm\else\textpm\fi{}0.10 MHz, which is in excellent agreement with previous results.

Depolarization of 6P322 cesium atoms, induced in collisions with noble gases

J. Guiry, L. Krause

Cross sections for relaxation of circular and linear polarization of $6^{2}P_{\frac{3}{2}}$ cesium atoms, induced in collisions with ground-state He, Ne, Ar, and Xe, have been determined by Zeeman scanning techniques. A fluorescence cell containing low-pressure cesium vapor together with a buffer gas was irradiated with circularly or linearly polarized 8521-\AA{} Cs resonance radiation, producing excited and polarized Cs atoms which became depolarized in subsequent collisions with the buffer-gas atoms. The resulting depolarization of the cesium resonance fluorescence was monitored in relation to buffer-gas pressure (0-10 Torr) and to the strength of the ambient magnetic field (0-10 kG). At low fields at which the nuclear spin $\stackrel{\ensuremath{\rightarrow}}{\mathrm{I}}$ is coupled to the electronic angular momentum $\stackrel{\ensuremath{\rightarrow}}{\mathrm{J}}$, the measurements yielded depolarization cross sections $Q(\mathrm{circ}.)$ and $Q(\mathrm{lin}.)$, which agree within experimental error with theoretical values calculated for spin-coupled conditions. At kilogauss fields with $\stackrel{\ensuremath{\rightarrow}}{\mathrm{I}}$ and $\stackrel{\ensuremath{\rightarrow}}{\mathrm{J}}$ decoupled, the experiments produced cross sections for disorientation and disalignment, which are also in satisfactory agreement with the appropriate theoretical predictions. The results indicate that the nuclear spin has a more pronounced effect on the collisional relaxation of the atomic dipole than of the quadrupole.
