The clock uses a rubidium vapor lamp and a glass cell containing rubidium. A voltage-controlled oscillator excites the cell with a 6.8 GHz signal. Rubidium atoms can exist in three states.

Ultra-precise rubidium atomic clocks are so stable that they lose less than one second over 3.7 million years. The metal is also widely used in medical research for imaging tumor cells.

Rubidium is an alkali metal in group IA of the periodic table with atomic number 37, an atomic weight of 85.47, and a density of 1.53 Mg/m 3. Its melting point is 38.9 C, and it boils at 688 C. The ...

Using rubidium-82 for medical purposes dates back to 1954, according to a 2015 study by Jean-François Chatal, et al., a group of French medical researchers, published in Frontiers in Medicine in ...

CLUMPED AND COLD Stanford University physicists used images like this one, which depicts the concentration of rubidium atoms, to determine that they had cooled the atoms to a record-low temperature.

To do this, they put it in an optical cavity and shine some light on it. If the rubidium atom is in one state, the light has the right wavelength to excite it to a higher energy state.
