Electron-impact ionization of helium for equal-energy-sharing kinematics
The close-coupling approach to electron-helium single ionization is analyzed and several ways of defining the scattering amplitudes are determined, for both equaland unequal-energy outgoing electrons. Nevertheless, the various definitions all lead to the same cross section. The convergent close-coupling sCCCd method with Laguerre sCCC-Ld and box-based sCCC-Bd target functions is applied to calc...
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 کاملElectron energy spectra from intense laser double ionization of helium.
The double ionization of helium in the strong-field limit has been studied using an electron-ion coincidence technique. The observed double ionization electron energy spectra differ significantly from the single ionization distributions. This gives new support to the rescattering model of double ionization and explicitly reveals the role of backward electron emission following the e-2e ionizing...
متن کاملElectron-impact double ionization of a model helium atom
Singleand double-ionization processes in electron scattering from a model helium atom are calculated by a direct solution of the time-dependent Schrödinger equation on a 3D lattice. The Coulomb interaction between the electrons is described by v(r1 ,r2)51/r. and all angular momenta are set to zero. The initial state is a product of the ground state of the model helium atom on a 2D lattice with ...
متن کاملElectron-impact double ionization of helium at high energies
Electron-impact double-ionization cross sections for the helium atom are calculated by direct solution of a nine-dimensional Schrödinger equation using a time-dependent close-coupling method. Previous calculations are extended to higher incident electron energies using a simple factor-of-2 reduction in the mesh spacing for the three-dimensional radial lattice. The recent calculations, computati...
