Usage examples of rubidium.
On the other hand, the leaves which had been immersed in the solutions of the chloride of rubidium and magnesium, of acetate of strontium, nitrate of barium, and citric acid, were quickly acted on by the phosphate.
Because of all of these technological hurdles, it wasn't until 1995 that experimenters were able to force rubidium atoms to form this type of condensate.
Popular choices for these bosons include specific isotopes of atoms of helium, sodium, rubidium, and hydrogen.
The initial method of making a rubidium condensate is the most straightforward, and further methods have been refinements of the same general principles of cooling.
Of all the materials used, rubidium was the easiest to make into a BEC because its atoms are the largest—they achieve low velocities at the highest temperature (energy) because mass relates to energy (hydrogen was the hardest BEC to form, but researchers think it may have superior applications because of its small size).
