Abstract
Abstract The effect of plasma screening on the electronic and vibrational properties of the H 2 + molecular ion was analyzed within the Born–Oppenheimer approximation. When a molecule is embedded in a plasma, the plasma screens the electrostatic interactions. This screening is accounted in the Schrodinger equation by replacing the Coulomb potentials with Yukawa potentials that incorporate the Debye length as a screening parameter. Variational expansions in confocal elliptical coordinates were used to calculate energies of the 1 s σ g and 2 p σ u states over a range of Debye lengths and bond distances. When the Debye length is comparable to the equilibrium bond d...
