Many years ago while I was at the Czech Technical University in Prague I
conducted an experiment involving propagation of acoustic waves in low
temperature plasma. It was observed that when a low frequency (168Hz)
acousic wave propagated in a gas discharge and the pertubation current was
displayed versus the DC current it exibited peaks corresponding to gas
mixtures (such as air) while no peaks were observed in pure gas. This was
part of my disertation. Due to the events in 1968 I had to interrupt this
research and leave that country. I have not had an opportunity to continue
this investigation ever since. Yet, I would be wery interested to learn if
any research has been done in this or similar area. If anybody has any
information or interest I would very much appreciate hearing from you.
