Effects of Screening and Pressure Ionization on the Electron Broadening of Spectral Lines in Dense Plasmas
Julian P. Kinney, Stephanie B. Hansen, Thomas A. Gomez +1
Collisions between electrons and radiating atoms broaden spectral absorption and emission lines in dense plasmas. High densities also introduce screening and pressure ionization ef…
