Quantum-statistical T-matrix approach to line broadening of hydrogen in dense plasmas

The electronic self-energy Se is an important input in a quantum-statistical theory for spectral line profile calculations. It describes the influence of plasma electrons on bound state properties. In dense plasmas, the effect of strong, i.e. close, electron-emitter collisions can be considered by t...
