So the IP value is related to the electronic structure and is one of the fundamental parameters of the atom. We introduced a new experimental method to measure the Rydberg state energy levels of 87Rb atom and got its rst ionization potential to be 33 690.946(7) cm??1.展开更多

So the ultracold plasma provides an ideal environment for the study of strongly coupled systems, where the Coulomb interaction is comparable with the thermal kinetic energy.展开更多
