Absorption and dispersion signals of D2 lines of rubidium atoms in a vapor cell have been experimentally investigated with the modulation transfer spectrum (MTS). Normal dispersion was observed at the transitions of Fg ? Fe = Fg - 1 and Fg ? Fe = Fg; anomalous dispersion, at transitions of Fg ?Fe = Fg + 1; and crossover resonance, by the transitions of Fg ?Fe = Fg - 1 and Fg ? Fe = Fg. The sign...

We report on the experimental realization of the storage of images in a hot vapor of Rubidium atoms. The images are stored in and retrieved from the long-lived ground state atomic coherences. We show that an image impressed onto a 500 ns pulse can be stored and retrieved up to 30 mus later. The image storage is made robust to diffusion by storing the Fourier transform of the image.

The title compound, Rb+·H3CN2O-, has been crystallized in liquid ammonia as a reaction product of the reductive ammonolysis of the natural compound streptozocin. Elemental rubidium was used as reduction agent as it is soluble in liquid ammonia, forming a blue solution. Reductive bond cleavage in biogenic materials under kinetically controlled conditions offers a new approach to gain access to s...

In its ground state, rubidium (Rb) has a single 5s electron outside a closed shell; the principal structure of its excited states is therefore similar to that of hydrogen. The first excited state is split in two by the spin-orbit interaction, and each of these levels is split further by the hyperfine interaction. Neglecting relativistic and reduced-mass effects, the Hamiltonian consists of four...

In yeast cells, of which the intracellular potassium had been partly replaced by rubidium or caesium, the intracellular ion distribution was studied by means of energy-dispersive X-ray microanalysis. The cells were rapidly frozen and thin sections were cut at low temperature on a cryo-ultramicrotome without the use of a trough liquid. By this dry cryosectioning procedure, complete retention of ...

In 1950, French physicist Alfred Kastler introduced the concept of modern optical pumping, for which he was awarded the Nobel Prize in 1966. The process of optical pumping involves using photons of a desired wavelength and polarization to change the distribution of a gas of atoms from thermal equilibrium. Today, optical pumping is a critical tool in modern Physics experiments, and is the basis ...
