Properties of the ground state of the hydrogen molecular ion

Physical Review A, 1998
The ground-state energies of the ions ${\mathrm{H}}_{2}^{+}$ and ${\mathrm{D}}_{2}^{+}$ have been calculated without making use of the Born-Oppenheimer approximation. Instead, the ions are treated as three-body systems whose ground states are spherically symmetric.

Quadrupole moment in the ground state of atomic hydrogen

Journal of Physics B: Atomic and Molecular Physics, 1984
The quadrupole moment of the atomic hydrogen ground state is calculated. It arises due to a hyperfine interaction. Its true value is 20 times larger than the result obtained only taking into account the hyperfine mixing with the lowest d level.

Accurate potential for the ground state of the hydrogen molecule

Spectrochimica Acta Part A: Molecular Spectroscopy, 1988
Abstract Starting from the spectroscopic constants, an electronic potential for the ground state hydrogen molecule is presented. Self-consistence is checked by numerical integration of the radial wave equation. The mean eigenvalue deviation is about 1 cm −1 . Comparison with the latest theoretical work is considered.

Collisional Excitation of Ground State Hydrogenic Ions

Canadian Journal of Physics, 1973
The nonrelativistic Coulomb–Born approximation has been used to compute scaled collision strengths for electron impact excitation of the 1s → ns, np, nd transitions in hydrogenic ions. Results are given for n = 2, 3, 4, 5, 6, [Formula: see text] as a function of the incident electron energy in threshold units.

Ground state calculations for solid hydrogen and deuterium

Zeitschrift für Physik A Hadrons and nuclei, 1972
The ground state energy, the mean square displacement of the molecules, the lattice constant, and the effective quadrupole-quadrupole coupling constant are calculated variationally and compared with the experiments. Both the orientationally ordered fcc-phases and the hcp-phases are considered.

Nonadiabatic effects in the ground state of the hydrogen molecule

Journal of Molecular Spectroscopy, 1974
Abstract A sum-over-states procedure is used in the ab initio evaluation of the matrix elements needed for a nonadiabatic treatment of the ground electronic state of H2. Bunker's (J. Mol. Spectrosc. 42, 478 (1972)) semiempirical value for the nonadiabatic parameter l1 = 0.130 ± 0.006 is in agreement with the present calculation, which therefore ...

Molecular Orbitals for the Hydrogen Molecule Ground State

The Journal of Chemical Physics, 1955
The ground-state energy of the hydrogen molecule has been calculated using a wave function constructed from LCAO molecular orbitals. The effective nuclear charge in the MO for one electron is taken to be different from that for the MO for the second electron.

Differential polarizability in the ground state of the hydrogen atom

Proceedings of the Physical Society, 1967
The differential polarizabilities in the ground states of hydrogen and the alkalis are discussed. General angular momentum arguments are used to separate the contributions from the different hyperfine-structure interactions. Three separate polarizabilities are introduced and their contributions to the quadratic Stark effect are given.
