Show Abstract
Absolute atomic hydrogen and methyl radical production resulting from direct electron impact dissociative excitation of CH4 has been measured in pulsed discharge by two-photon allowed laser induced fluorescence. For 20 Torr pure methane discharge with 480 ns pulse duration, 4–6 kV voltage applied, and 6–11.5 mJ input electrical energy yield of 10–22×1015 cm−3 hydrogen atoms, i.e., up to 4.5% dissociation of CH4 is achieved by direct electron impact with 50% energy conversion efficiency. © 2004 American Institute of Physics.
