We demonstrate a tunable narrowband filter based on optical-pumping-induced circular dichroism in rubidium vapor. The filter achieves a peak transmission of 14.6%, a linewidth of 80 MHz, and an out-of-band extinction of >or=35 dB. The transmission peak can be tuned within the range of the Doppler linewidth of the D1 line of atomic rubidium at 795 nm. While other atomic filters work at frequenci...

After various earlier attempts with different radiotracers 51chromium and finally ^IndiumoKİne became the tracers of choice for the radiolabeling of human platelets and the subsequent monitoring of in vivo kinetics. Data on clinical application of platelet survival in atherosclerotic vascular disease and a variety of risk factors are presented. Furthermore, a new approach to use nonradioactive ...

Rubidium metaborate, Rb3B3O6, was obtained by the reaction of Rb2CO3 and BN using a radiofrequency furnace at a maximum reaction temperature of 1173 K. The crystal structure has been determined by single-crystal X-ray diffraction. The space group is R3c, with all atoms positioned on a twofold axis (Wyckoff site 18e). The ionic compound is isotypic with Na3B3O6, K3B3O6 and Cs3B3O6.

The title compound, Rb(8)[W(2)O(4)(SO(4))(6)], was precipitated from a melt of tungsten(VI) oxide and rubidium sulfate in rubidium disulfate. The unit cell contains two discrete [{W(VI)O(2)(SO(4))(2)}(2)(μ-SO(4))(2)](8-) units connected by Rb-O coord-ination. The W atom is octahedrally surrounded by two oxide ligands, two terminal sulfate ligands and two bridging sulfate groups. One Rb atom is ...

A Rubidium high-frequency lamp is used as the pumping light source to excite Rubidium atoms in a sample cell. The pumping source light is filtered to transmit the D1 Rb line and polarizers are used to produce circular polarization. The circular polarization pumping mechanism selectively repopulates the sample cell ground state Rb Zeeman hyperfine levels away from thermal equilibrium populations...

We report on the synthesis and the physical properties of Ba1−xRbxTi2Sb2O (x ≤ 0.4) by x-ray diffraction, superconducting quantum interference device magnetometry, resistivity, and specificheat measurements. Upon hole doping by substituting Ba with Rb, we find superconductivity with a maximum Tc=5.4 K. Simultaneously, the charge-density-wave transition temperature is strongly reduced from TCDW�...
