Abstract :
Summary form only given. The variable-phase approach is applied to scattering and bound states in screened Coulomb potentials in three and two dimensions. A proper account of scattering eliminates discontinuities in thermodynamic properties of the electron-hole system whenever bound states disappear due to screening. This consistent treatment of bound states and scattering allows us to estimate the distribution of electron-hole pairs between correlated and free-carrier states.
