Optically pumped atomic spin orientation and the law of mass action for 2Cs⇄Cs2

J. J. Ho, Chongye Wang, Robert A. Bernheim

The effect of optically pumped atomic spin orientation on the atom–dimer equilibrium in cesium vapor has been observed. Such a shift in equilibrium was predicted over two decades ago and is due to the redistribution of spin-determined bonding and antibonding collision trajectories. Orientation of the total spin angular momentum of 6 2S1/2 ground state Cs atoms in the vapor phase was produced by optical pumping with a tunable cw dye laser. A decrease in the equilibrium molecular density resulted and was measured using laser induced fluorescence from the B 1Πu state. The shift in equilibrium is a function of the degree of atomic orientation and could be observed in the temperature range 383–421 K for cesium vapor in a glass cell which also contained a He–N2 buffer gas mixture with a composition ratio of 9:1.The effect of optically pumped atomic spin orientation on the atom–dimer equilibrium in cesium vapor has been observed.

Transverse magneto-optical compression of a frequency-chirping slowed cesium atomic beam

P. Pillet, Jia Yu, J. Djemaa +1 more

We have transversally compressed a monokinetic cesium atomic beam in a 2D magneto‐optical trap (MOT), also called a funnel, on the F=4→F’=5 transition of the cesium D2 line. The longitudinal cooling is obtained by frequency‐chirping. Preliminary results show a final diameter of about 50–100 μm with a density of a few 108 atoms/cm3 for slowed atoms. The density is enhanced by a preliminary orientation of the atoms inside the trap.

Frequency shift of the magnetic resonance in 5s 2 S 1/2 rubidium atoms due to spin-exchange collisions with optically oriented cesium atoms

Sergei P. Dmitriev, N. A. Dovator

For the case of cesium atoms optically oriented in a mixture of cesium and rubidium vapors, the temperature dependence of the frequency shift of a magnetic resonance excited in a set of Zeeman sublevels for two hyperfine states of 87Rb 5s 2 S 1/2 atoms. It is shown that, in a weak magnetic field of about 2 × 10−6 T, this shift is determined by the spin-exchange interaction of rubidium atoms with optically oriented 133Cs atoms.
