Comment on “Electron impact ionization of helium isoelectronic systems”

چکیده
In a recent paper [1], Talukder proposed a new empirical formula for electron-impact ionization cross sections of He-like ions that was claimed to excellently agree with the available experimental and theoretical data. Discussing this agreement, the author of reference [1] makes extensive comparison with our recommended formula of reference [2] (referred to as “BRY” in [1] although it would be more appropriate to use “BRM”) and comes to a conclusion that it fails to describe experimental data both in magnitude and in the dependence on the electron energy.

متن کاملA model for the charge transfer probability in helium nanodroplets following electron impact ionization
A theoretical model has been developed to describe the probability of charge transfer from helium cations to dopant molecules inside helium nanodroplets following electron impact ionization. The location of the initial charge site inside helium nanodroplets subject to electron impact has been investigated and is found to play an important role in understanding the ionization of dopants inside h...
متن کاملElectron-impact single and double ionization of helium
Electron-impact ionization cross sections for helium are calculated using time-dependent close-coupling theory. The total wave function for the three electron system is expanded in nine dimensions, where three dimensions are represented on a radial lattice and a coupled channels expansion is used to represent the other six dimensions. Collision cross sections are obtained by t→` projection onto...

The binary-encounter dipole ~BED! model for electron-impact ionization is applied to helium using the continuum dipole oscillator strength calculated from the relativistic random-phase approximation. The resulting total ionization cross section agrees with available experimental data well within the quoted experimental uncertainties. The singly differential (5energy distribution of ejected elec...
متن کاملTime-dependent close-coupling calculations for the electron-impact ionization of helium
Electron-impact ionization cross sections for helium are calculated using time-dependent close-coupling theory. In a frozen-core approximation, the wave function for the three-electron system is expanded in terms of two-electron wave functions which fully describe the ejected and scattered electrons at all times following the collision. The resulting close-coupled partial differential equations...
