Modeling Dusty Plasma Discharges of Noble Gases Using a Self
... Neon and xenon have six excitation levels compared to argon and helium that only have one. Moreover, all of the excitation levels are at lower energies than that required for ionization. Therefore, energy losses for neon and xenon extended further into the bulk and were not contained to locations of ...
