The article focuse son how a clamp-on ultrasonic flowmeter is helping firms to make the most of helium due to rising prices. The helium atom is smaller than any other element and second only to the hydrogen atom in lightness. Helium is chemically inert and does not form stable compounds with other elements. The attractive forces between helium atoms are weak and has the lowest liquefaction temperature of all the permanent gases.

    Helium metastable atom density was spatially determined by a modified electrostatic probe in a remote plasma. The probe structure was similar to that of a guard ring probe. Opposite polarity voltages were applied to the inner probe and the guard ring to shield both electrons and ions from the...

    We propose the explanation of a small yet finite frequency shift of a hyperfine transition in two-dimensional atomic hydrogen bound to the surface of superfluid helium at T < 0.1 K. The nonzero shift is caused, first, by the interaction between adsorbed atoms, which effectively reduces their...

    We have developed a novel, high flux source of metastable rare gas atoms (helium, neon and argon) that uses liquid helium cooling to reduce the initial atomic velocity. Fluxes exceeding 1014 atoms/ster/s with He and Ne were obtained. With average velocities of ∼600 m/s for He and ∼300...

Indication that these effects lead to interesting consequences, such as the complete...
