Effective oscillator strength distributions are systematically generated and tabulated for the
alkali atoms, the alkaline-earth atoms, the alkaline-earth ions, the rare gases and some …

Van der Waals interaction is an elusive many-body effect arising from instantaneous charge
fluctuations. Fundamental understanding of this effect plays an important role in …

The dispersion coefficients for the van der Waals interactions between the rare gases Ne, Ar,
Kr, and Xe and the low-lying states of Li, Na, K, and Rb are estimated using a combination of …

The polarizabilities of the low lying states of the Mg+ and Ca+ ions are evaluated by
diagonalizing the semi-empirical Hamiltonians in a large dimension single electron basis …

The five longest tune-out wavelengths for the potassium atom are determined using a
relativistic structure model which treats the atom as consisting of a single valence electron …

The scalar and tensor dynamic polarizabilities of the first excited P 1∕ 2, 3∕ 2 2 states of
the alkali-metal atoms Na, K, and Rb are calculated using relativistic many-body …

We present a new three-dimensional potential energy surface (PES) for the electronic
ground state of the LiH+ H⇌ Li+ H2 reaction and further analyze specific aspects of the lower …

A general procedure for systematically evaluating the long-range dispersion interaction
between two heteronuclear atoms in arbitrary states is outlined. The C 6 dispersion …

The properties of a number of states of calcium are determined from a large basis
configuration interaction calculation. The main focus is on the polarizabilities of the low lying …

The far wings of the sodium spectra arising from the collisional broadening of the D lines by
ground helium atoms are investigated theoretically. The required X 2 Σ+, A 2 Π and B 2 Σ+ …
