Optical pumping of rubidium atoms frozen in solid argon
We have grown crystals of solid argon doped with rubidium atoms. The spectrum of the implanted atoms depends on the crystal-growth temperature and annealing history. We have used optical pumping to polarize the spin state of the implanted atoms and polarization spectroscopy to detect the spin state and measure the spin-relaxation time. In addition to the desired optical pumping, we also observe...
متن کاملDiffusion of hydrogen fluoride in solid parahydrogen.
We studied diffusion of hydrogen fluoride (HF) in solid parahydrogen (pH2) around 4 K. Diffusion rates were determined from time dependence of FT-IR spectra of HF monomers. The absorption of HF monomers shows temporal decay due to dimerization reaction via diffusion. It was found that the rates are affected by the sample temperature, the initial HF concentration, and annealing of samples. The o...
متن کاملOptical Pumping of Rubidium Vapor Atoms
The Zeeman splittings of the hyperfine structure of rubidium as well as the ambient geomagnetic field are investigated by using an optical pumping apparatus. The frequencies of Zeeman transitions are proportional to the magnetic field applied; using this, the ambient geomagnetic field is found to be B = ((37.755±0.025)ex+(5.5179±0.0030)ey +(19.15±0.06st±0.67sy)ez) ·10−6 T, compared to an accept...
متن کاملHigh flux source of cold rubidium atoms
We report on the production of a continuous, slow, and cold beam of Rb atoms with an extremely high flux of 3.2 1012 atoms/s, a transverse temperature of 3 mK, and a longitudinal temperature of 90 mK. We describe the apparatus created to generate the atom beam. Hot atoms are emitted from a rubidium candlestick atomic beam source and transversely cooled and collimated by a 20 cm long atomic coll...
متن کاملLight-induced collisions of ultracold rubidium atoms
In this dissertation I present a variety of experiments on collisions between ultra-cold rubidium atoms. These collisions take place in light-force atom traps, where temperatures below 1 mK are reached. At these low temperatures weak, long-range interactions between the atoms are important, and collision times are long. Consequently, the absorption and spontaneous emission of photons plays an i...
