A modified C-field circuit for the rubidium atomic clock

open access: yesAIP Advances, 2021
As one of the important circuits of the rubidium atomic clock, the C-field circuit plays a significant role in the rubidium atomic clock’s performance. Generally, a C-field circuit is used to provide a constant current to a C-field coil by forming a weak

Observation of the 87Rb 5S1/2 to 4D3/2 electric quadrupole transition at 516.6 nm mediated via an optical nanofibre

open access: yesNew Journal of Physics, 2020
Light guided by an optical nanofibre has a very steep evanescent field gradient extending from the fibre surface. This gradient can be exploited to drive electric quadrupole transitions in nearby quantum emitters.

Interferometric measurement of the resonant absorption and refractive index in rubidium gas [PDF]

open access: yes, 2006
We present a laboratory demonstration of the Kramers-Kronig relation between the resonant absorption and refractive index in rubidium gas. Our experiment uses a rubidium vapor cell in one arm of a simple Mach-Zehnder interferometer.

Rubidium tetrafluoridobromate(III): redetermination of the crystal structure from single-crystal X-ray diffraction data

open access: yesIUCrData, 2019
Single crystals of rubidium tetrafluoridobromate(III), RbBrF4, were grown by melting and recrystallizing RbBrF4 from its melt. This is the first determination of the crystal structure of RbBrF4 using single-crystal X-ray diffraction data.

Neutron Resonance Parameters of Rubidium-85 and Rubidium-87 [PDF]

open access: yesJournal of Nuclear Science and Technology, 1984
High resolution neutron transmission and low background capture measurements were carried out on the separated rubidium isotopes, using the time-of-flight facility of the linear accelerator of Japan Atomic Energy Research Institute. Resonance parameters and associated quantities were deduced as follows: For 85Rb, gΓ n values were determined for 138 ...
