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 کاملSimultaneous ionization-excitation of helium to He„2p... magnetic sublevels by proton impact
Experimental magnetic substate cross section ratios s0 /s1 and scattering angle-integrated cross sections following ionization-excitation of helium to He(2p) P in H1He collisions have been determined, using polarization measurements of emitted radiation in the extreme ultraviolet region in combination with total cross sections, over a wide range of proton velocities ~2–6 a.u.!. These results ar...
متن کاملDouble Ionization of He by Proton Impact
Double ionization of helium by charged particle impact belongs to the most simple and therefore fundamental, unsolved dynamical many-electron problems in atomic physics. At medium to small perturbations (Z/v < 1; Z, v projectile charge and velocity) mainly two mechanisms contribute to the double ionization cross section: First, one electron can be ionized directly by the interaction with the pr...
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 کاملDoubly differential cross sections for the proton- impact double ionization of helium
A time-dependent close-coupling approach is used to investigate 6 MeV proton-impact double ionization of helium. We extract doubly differential (in the emission angles of both outgoing electrons) cross sections for comparison with recent experimental measurements. Good qualitative agreement is found between our calculations and the measurements. We also present differential cross sections for c...
