UV Fe I absorption in the carbon-iron arc periphery under formation of carbon-encapsulated iron nanoparticles

The UV (384.5 − 393.1 nm) absorption spectra of Fe I atoms (21 lines) originating from a 5D0-4, a 5F1-4 and a 3F2-3 electronic levels were used to determine the Fe I column density in function of carbon-iron anode composition and the distance from the arc gap, beneath and above the horizontally orie...

Summary:The UV (384.5 − 393.1 nm) absorption spectra of Fe I atoms (21 lines) originating from a 5D0-4, a 5F1-4 and a 3F2-3 electronic levels were used to determine the Fe I column density in function of carbon-iron anode composition and the distance from the arc gap, beneath and above the horizontally oriented electrodes. The results revealed a wide variation between the gradients of Fe I column density above and below the arc zone. Also the electronic excitation temperature of the Fe I levels was evaluated.
