Variational Average-Atom in Quantum Plasmas (VAAQP) – Application to radiative properties

We present an application of the Variational Average-Atom in Quantum Plasmas (VAAQP) model and numerical code to dense plasmas radiative properties. We propose an approximate Detailed Configuration Accounting (DCA) approach starting from the variational model of configurations in jellium. This leads to a simplified model which is qualitatively different from those which usually stem from the atom-in-cell approach. It is also shown that, with some additional approximations, the DCA calculation can be handled by use of the Gaussian approximation to perform a statistical approach to the spectrum. Our purpose here is to show that this model provides a simple way to calculate the radiative properties and is likely to give realistic results.
