Dynamic Hydrogen Ionization
We investigate the ionization of hydrogen in a dynamic Solar atmosphere. The simulations include a detailed non-LTE treatment of hydrogen, calcium and helium but lack other important elements. Furthermore, the omission of magnetic fields and the one-dimensional approach make the modeling unrealistic in the upper chromosphere and higher. We discuss these limitations and show that the main result...
متن کاملMicrowave ionization of hydrogen atoms
Figure 1: Fraction of ionized hydrogen atoms as a function of microwave frequency , measured in units of level spacing for initially excited level ; data are obtained by numerical simulations of classical (circles) and quantum (crosses) evolution; one-photon ionization threshold is marked by (from [3]) Dima Shepelyansky (2012), Scholarpedia, 7(1):9795. doi:10.4249/scholarpedia.9795 revision #12...
متن کاملHydrogen pair-ion production by catalytic ionization
Pair plasmas consisting of only positiveand negative-charge particles of equal mass have attracted special attention because they maintain space-time symmetry. A fullerene pair-ion plasma, consisting of positive and negative ions of equal mass (C60 and C60), has been generated and its collective phenomena have been investigated experimentally [1]. In order to investigate more extensive physical...
متن کاملStochastic Ionization of Relativistic Hydrogen-like Atom
Stochastic ionization of higly excited relativistic hydrogenlike atom in the monochromatic field is considered. A theoretical analisis of chaotic dynamics of the electron based on Chirikov criterion is given. Critical value of the external field is evaluated analitically. ∗e-mail: [email protected]
متن کاملCatalytic Effect on Ionization of Hydrogen
In a plasma source development of a hydrogen pair-ion plasma consisting of only hydrogen atomic ions, H and H−, efficient production of the atomic ions is required. Hydrogen positive ions produced in a PIG discharge are supplied to a catalyst. The ions are converted to the atomic ions on the catalyst surface, and an ionic plasma with very low electron density is generated.
