Dispersion coefficients for interactions among H, Li, Na, K atoms with Debye–Hückel potentials

Excitons and the Positronium Negative Ion: Comparison of Spectroscopic Properties

“…Knowledge of the Van der Waals two-body dispersion coefficients in the multipole expansion of the second-order long-range interaction between a pair of atoms is of utmost importance for the quantitative interpretation of the equilibrium properties of gases and crystals, of transport phenomena in gases, and of phenomena occurring in slow atomic beams ( [93,[100][101][102], references therein). The long-range part of the interaction potential between two spherically symmetric atoms a and b separated by a distance R can be written as a series with coefficients C n denoted as dispersion coefficients [93,[100][101][102]:…”

Broadening of radiative transitions in charge exchange collisions of one-electron atomic ions and bare nuclei, also H − + H (T) (Devdariani 2014).…”

Energies and transition wavelengths for two-electron atoms under Debye screening

“…In recent years, there has been an increasing interest in the study of atomic systems under the influence of screened Coulomb potentials ( [1][2][3][4][5][6][7][8][9][10], references therein). The screened Coulomb potential can be represented by different models.…”
