Double ionization of Li-like ions by high-energy photons
The processes of double ionization by absorption or inelastic (Compton) scattering of a photon from atomic systems are of fundamental interest. This is due to the fact that the two-electron emission is exclusively caused by the electron-electron interaction, the accurate treatment of which is still one of the main tasks for different theoretical approaches. As a target, it is usual to use the n...
متن کاملDirect excitations of He+ and Li++ ions by collisions with protons or antiprotons
The impact parameter formalism of the single-center close-coupling, first-, and second-order Born approximations have been applied to investigate direct excitations of Helium He+(2s) and Lithium Li++(2s) ions by colliding with protons or antiprotons. The total 3s, 3p, and 3d scaled excitation cross sections are calculated in the scaled impact energy region (2 to 1000 keV). The present work aims...
متن کاملCalculation 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 کاملNeutron-impact ionization of He
The double ionization of He by either photon impact or bare ion impact are simple examples of the quantal three-body Coulomb breakup problem. For example, the double photoionization of He near threshold produces two slow moving continuum electrons in the Coulomb field of an alpha particle, which is extremely difficult for perturbation theory to handle. On the other hand, various non-perturbativ...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
