Field dependent line emission in magnetized plasmas

The magnetic field 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 the magnetic field dependent eigenvalues and eigenstates in a non-perturbative fashion by diagonalizing the Hamiltonian with the magnetic field interaction. The result of this calculation produces field dependent atomic states 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 calculations for line emission in Neon-like iron ions and magnetic fields in the megagauss range for comparison with measurements in experiments driven by the 1 MA Zebra pulse power generator.
