Field dependent line emission in magnetized plasmas

The magnetic field mixing effect on the atomic states and line emission of radiators in plasmas is a potential diagnostic tool for field measurements in laboratory and astrophysical plasmas. To model this effect, we calculate magnetically induced line transition radiative decay rates using relativistic multiconfiguration atomic structure. The result of this calculation produces field dependent atomic state transitions that include the characteristic mixing of the magnetic field. Further, these atomic states can be used to calculate the line emission spectrum. The latter shows changes in the field free spectrum, including line intensities that are dependent on the magnetic field strength. We perform modeling calculations for line emission in neon-like iron ions and magnetic fields in the mega gauss range for comparison with measurements in experiments driven by the 1 MA Zebra pulse power generator.
