Greetings ! This is not really a discussion thread, I just wan'na ask a question and hope someone could finally help me with this because I couldn't find this info during the several months I occassionaly tried to search for it (even briefly studied a Hall Effect thruster thesis). I need the ionisation cross-section and the Debye lenght (for ion rich plasma) of Xenon. Also, precise formulas of electron free paths in Xenon plasma at the density and pressure of a typical HET or IBT would be helpfull if you got'em (I have some formulas, but without the above data they're not of much use and they're pretty complex for me right now.) Thanks a lot. Live long and prosper.
