Abstract:

The spectral line shapes for hydrogen-like heavy ion emitters embedded in strongly correlated two-component electron-ion plasmas are investigated with numerical simulations. For that purpose the microfield fluctuations are calculated by molecular dynamics simulations where short range quantum effects are taken into account by using a regularized Coulomb potentialfor the electron-ion interaction. The microfield fluctuations are used as input in a numerical solution of the time-dependent Schrödinger equation for the radiating electron. In distinction to the standard impact and quasistatic approximations the method presented here allows to account for the correlations between plasma ions and electrons. The shape of the Lyα-line in Al is investigated in the intermediate regime. The calculations are in good agreement with experiments on the Lyα-line in laser generated Al plasmas.
