Using the Pekeris-like method, the ground state wave functions $\Psi$ of the helium-like atoms with nucleus charge $1\leq Z\leq5$ are Ordnungszahl: 2. Dichte (g/L):.

Liquid Helium is called a "quantum fluid" as it displays atomic properties on a macroscopic scale. The viscosity of liquid helium is 25 micropoises (water has a viscosity of 10,000 micropoises). As helium is cooled below its transition point, it has an unusual property of superfluidity with a viscosity approaching zero micropoises.

Improving mass accuracy. In a commentary written to accompany the research, Niels Madsen of Swansea University in the UK points out that Hori’s group has previously achieved record precision for the antiproton-to-electron mass ratio by replacing one electron in a helium atom with an antiproton. Atomic radius decreases as you go across a period from left to right. Across the periodic table Lowest atomic radius: helium(2) : 31 pm.
