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 کاملEstimation of second virial coefficients for rare gases in thermodynamic views
Using the Gaussian 2003 software and MP2/ 6–311 ++ G** method for He: He, Ne:Ne andMP2/6-31G method for Ar: Ar, Kr: Kr and HF/STO-3G method for Xe: Xe, the optimizedinteraction energies between two like atoms of rare gases (He, Ne, Ar, Kr and Xe) as a functionof the distances between the centers of two considered atoms were evaluated and the resultswere interpreted according to the Lennard – Jo...
متن کاملPhotoionization of helium nanodroplets doped with rare gas atoms.
Photoionization of He droplets doped with rare gas atoms (Rg=Ne, Ar, Kr, and Xe) was studied by time-of-flight mass spectrometry, utilizing synchrotron radiation from the Advanced Light Source from 10 to 30 eV. High resolution mass spectra were obtained at selected photon energies, and photoion yield curves were measured for several ion masses (or ranges of ion masses) over a wide range of phot...
متن کاملIonization of Helium Near Threshold by Electron Impact
The threshold law for the cross section for ionization of simple monatomic gases by electron impact has recently been the subject of renewed interest 2. To date, studies of He+, using the retarding potential difference (RPD) technique 3 6 have been taken as support for, or interpreted with the aid of, a linear threshold law 7 , 8 . Recent studies with a 127° electrostatic energy selector have, ...
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...
