Solvation of positive atomic ions A+ is extremely important in many areas, ranging from
basic inorganic chemistry and electrochemistry to biochemistry. In recent years several …

The ion chemistry of helium currently embraces a large variety of species, mostly cationic,
which range from simple small-size molecular fragments or complexes to large-size cluster …

The definition of the van der Waals crust as the spherical section between the atomic radius
and the van der Waals radius of an element is discussed and a survey of the application of …

We report the production of ultracold heteronuclear Cs* Yb molecules through one-photon
photoassociation applied to an ultracold atomic mixture of Cs and Yb confined in an optical …

Quadrupole moment and dipole polarizability tensor components are calculated at the
