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…
Theoretical Study of Quantum Scattering Processes for Diatomic Hydrogen and Oxygen Complex
L. Wei, M. J. Jamieson, A. Dalgarno
We present a quantum mechanical study of the diatomic hydrogen and oxygen collision and energy transfer for its four molecular symmetry $(X^{2}Π, ^{2}Σ^{-}, ^…
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…
Rate coefficients for rovibrational transitions in H_2 due to collisions with He
N. Balakrishnan, M. Vieira, J. F. Babb +3
We present quantum mechanical and quasiclassical trajectory calculations of cross sections for rovibrational transitions in ortho- and para-H_2 induced by collisions with He atoms.…
Variational calculations on the hydrogen molecular ion
J. M. Taylor, Zong-Chao Yan, A. Dalgarno +1
We present high-precision non-relativistic variational calculations of bound vibrational-rotational state energies for the and molecular ions in each of the lowest…
