Its atomic radius is 0.248 nm and the (+1) ionic radius is 0.148 nm. In the solid state Rubidium has a body-centered cubic crystal structure with a = 0.562 nm and a nearest neighbor distance of 0.478 ...

Rubidium atoms can behave unpredictably ... One of the study’s key insights is the influence of hyperfine structure on atomic collisions. Hyperfine structure results from the interaction between ...
