Helium Microwave Induced Plasma Mass Spectrometry For Detection Of Metals And Nonmetals In Aqueous Solutions

A helium microwave induced plasma is evaluated as an ion source for plasma mass spectrometry. Analyte position studies were performed to assess background interferences and the distribution of analyte ions within the helium plasma as a function of nebulizer flow … Continue reading

Superfluid Helium In Three-Dimensional Counterflow Differs Strongly From Classical Flows: Anisotropy On Small Scales

Three-dimensional anisotropic turbulence in classical fluids tends towards isotropy and homogeneity with decreasing scales, allowing—eventually—the abstract model of homogeneous and isotropic turbulence to be relevant. We show here that the opposite is true for superfluid 4He turbulence in three-dimensional counterflow … Continue reading

Electric-field Induced Helium-Helium Resonances

The tunability of the helium-helium interaction through an external electric field is investigated. For a static external field, electric-field induced resonances and associated electric-field induced bound states are calculated for the 4He-4He, 3He-4He, and 3He-3He systems. Qualitative agreement is found … Continue reading
