*Any* gas exposed to a 140 kV spark will ionize. Even the most tightly bound of them (He) has a first ionization energy of only 24.6 eV. Furthermore, the energy required to ionize a Rydberg atom (not an inverse Rydberg atom), is a tiny fraction of the normal ionization energy (since the electron is already in a high orbit). For Inverse Rydberg Atoms OTOH the story is very different. These would have an ionization energy in the keV range. BTW for the sake of comparison the first ionization energy of Xe is 12.1 eV and Oxygen (atomic) 13.6 eV. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
