Chemi-ionization reactions involving metastable helium atoms at high energy
نویسنده
چکیده
Total chemi-ionization cross-sections have been measured over the 15 to 1 500 eV energy interval for collisions of He 2 1S and 2 3S metastable atoms with Ne, H2, N2, O2 and CO, using a slow ion measurement technique. With molecular targets these measurements have shown a strong energy dependence for the total ionization cross-section without dissociation. In the case of dissociative ionization an energy threshold appears, dependent on the energy defect of the reaction. J. Physique 44 (1983) 1263-1271 NOVEMBRE 1983, 1

Calculation of the total cross section for the ionization of H, He, Ne and Ar atoms by bare ions at the high energy range
In the present work, the total cross-section for the ionization of H, He, Ne and Ar atoms by +He2+ ، H+ ، Li3 ions has been calculated. In these calculations, a binary encounter approximation in the form of a two-body process between projectile ions and atomic electrons at the high energy range has been implemented. In order to enter the nuclear role of the target atom, the atomic electron vel...
متن کاملA theoretical study of the gas-phase chemi-ionization reaction between uranium and oxygen atoms.
The U+O chemi-ionization reaction has been investigated by quantum chemical methods. Potential-energy curves have been calculated for several electronic states of UO and UO(+). Comparison with the available spectroscopic and thermodynamic values for these species is reported and a mechanism for the chemi-ionization reaction U+O-->UO(+)+e(-) is proposed. The U+O and Sm+O chemi-ionization reactio...
متن کاملProduction of a degenerate Fermi gas of metastable helium-3 atoms
Most of this book discusses Fermi gases composed of alkali atoms. Since the first realization of a degenerate K Fermi gas in 1999, Li has been the only other fermionic atom to be cooled below the Fermi temperature. In this contribution we will discuss our recent results on cooling fermionic He below the Fermi temperature. This has not been performed with ground state He, but with He in the meta...
متن کاملRotationally induced Penning ionization of ultracold pho- toassociated helium dimers
– We have studied photoassociation of metastable 2S1 helium atoms near the 2 S1-2 P2asymptote by both ion detection in a magneto-optical trap and trap-loss measurements in a magnetic trap. A detailed comparison between the results of the two experiments gives insight into the mechanism of the Penning ionization process. We have identified four series of resonances corresponding to vibrational m...
متن کاملThe Possible Role of Penning Ionization Processes in Planetary Atmospheres
In this paper we suggest Penning ionization as an important route of formation for ionic species in upper planetary atmospheres. Our goal is to provide relevant tools to researchers working on kinetic models of atmospheric interest, in order to include Penning ionizations in their calculations as fast processes promoting reactions that cannot be neglected. Ions are extremely important for the t...
