Abstract
AbstractExtensive nonrelativistic studies have been performed on the spectral properties of confined atomic systems under a charge neutral background. The effect of confinement on the spectral properties due to the neutral background has been analyzed using plasma model, which, for weak coupling case, can be obtained from the standard Debye screening model, and for strong coupling case, can be envisaged by ion sphere (IS) model. Further consideration has been given for estimating the effect due to spatially confined plasma, which is obtained by imposing finite boundary conditions on the wave functions. Several atomic, ionic, and exotic systems have been considered for our exclusive study. The structural properties like the ground and excited state energies, oscillator strengths, and transition probabilities for low lying excitations and spectral line shifts have been estimated for hydrogen‐ and helium‐like ions under different plasma coupling strengths. The system approaches towards gradual instability with increase of the plasma coupling strength. A gradual reduction of the ionization potential is observed and the number of bound states become finite. The behavior of ionization potentials, excitation energies, polarizabilities, oscillator strengths, and transition probabilities with respect to increased plasma strength have been found to be interesting. Our findings are in good agreement with limited experimental observations using laser produced plasmas. © 2007 Wiley Periodicals, Inc. Int J Quantum Chem, 2007
