Theoretical Study of Pressure Broadening of Lithium Resonance Lines by Helium Atoms

Cheng Zhu, James F. Babb, Alex Dalgarno

Quantum mechanical calculations are performed of the emission and absorption profiles of the lithium 2s-2p resonance line under the influence of a helium perturbing gas. We use car…

High-precision calculations of van der Waals coefficients for heteronuclear alkali-metal dimers

A. Derevianko, J. F. Babb, A. Dalgarno

Van der Waals coefficients for the heteronuclear alkali-metal dimers of Li, Na, K, Rb, Cs, and Fr are calculated using relativistic ab initio methods augmented by high-precision ex…

The dipole polarizability of the hydrogen molecular ion

J. M. Taylor, A. Dalgarno, J. F. Babb

A procedure is described for the precise nonrelativistic evaluation of the dipole polarizabilities of H_2^+ and D_2^+ that avoids any approximation based on the size of the electro…
