Rubidium 85 has 37 electrons, only one of which is in the outermost shell. 85Rb is the only stable isotope of rubidium (although 87Rb is only very weakly unstable, and is thus efectively stable), and is the only isotope we consider in this reference.

Rubidium-85 atom is a stable isotope of rubidium with relative atomic mass 84.91179, 72.17 atom percent natural abundance and nuclear spin 5/2.

Properties and data of the isotope 85 Rb. See also: list of Rubidium isotopes. Direct parent isotopes are: 85 Kr, 85 Sr. Nuclear magnetic properties of the NMR active Nuclide 85 Rb. …

The RB-85 features 13 in. diameter tires and a tough, corrosion-resistant powder-coated steel frame to support an oversized 85 lb.-capacity hopper. A heavy-duty agitator breaks up clumps, while a foot-operated deflector shield keeps materials out of unwanted areas.

It is characterized by one valence electron. The natural abundance of Rubidium isotopes is 85 Rb (72.2%) and 87 Rb (27.8%). The spectra show the saturated absoption of the D 1 line of Rubidium at 795nm. The spectra are detected via one continuous scan with a Sacher Lasertechnik tunable diode laser system.

化学反应活性高，铷的化学性质与钾相似，但比钾活泼；与卤素、磷、硫等发生剧烈的化学反应，引起燃烧。 银白色蜡状软金属，含有杂质时则略带黄色。 熔点39℃；沸点688℃；d201. 532；硬度0.3。 铷的蒸气在180℃时绛红色，温度高于250℃时，则为橙黄色。 在潮湿空气中能自燃，遇水发生化学反应放出氢气和热量而引起燃烧爆炸。 化学反应活性高，铷的化学性质与钾相似，但比钾活泼；与卤素、磷、硫等发生剧烈的化学反应，引起燃烧。

In this reference we present many of the physical and optical properties of 85 Rb that are relevant to various quantum optics experiments. In particular, we give parameters that are useful in treating the mechanical effects of light on 85 Rb atoms.

2010年3月25日 · We describe our experimental setup for creating stable Bose-Einstein condensates of Rb-85 with tunable interparticle interactions. We use sympathetic cooling with Rb-87 in two stages, initially in a tight Ioffe-Pritchard magnetic trap and subsequently in a weak, large-volume crossed optical dipole trap, using the 155 G Feshbach resonance to ...
