Solving close-coupling equations in momentum space without singularities for charged targets
A. W. Bray, I. B. Abdurakhmanov, A. S. Kadyrov +2
The analytical treatment of the Greens function in the convergent close-coupling method [Bray et al. Comp. Phys. Comm. 203 147 (2016)] has been extended to charged targets. Further…
Timing analysis of two-electron photoemission
A. S. Kheifets, I. A. Ivanov, Igor. Bray
We predict a significant delay of two-electron photoemission from the helium atom after absorption of an attosecond XUV pulse. We establish this delay by solving the time dependent…
Different escape modes in two-photon double ionization of helium
A. S. Kheifets, I. A. Ivanov, Igor Bray
The quadrupole channel of two-photon double ionization of He exhibits two distinctly different modes of correlated motion of the photoelectron pair. The mode associated with the ce…
Convergent calculations of double ionization of helium: from (,2e) to (e,3e) processes
A. S. Kheifets, Igor Bray
The first absolute (e,3e) measurements, by Lahmam-Bennani et al [Phys. Rev. A {\bf 59}, 3548 (1999)], have been recently approximately reproduced by Berakdar [Phys. Rev. Lett. {\bf…
Electron-impact broadening of the 3s-3p lines in low-Z Li-like ions
Yu. V. Ralchenko, H. R. Griem, I. Bray
The collisional electron-impact line widths of the 3s-3p transitions in Li-like ions from B III to Ne VIII are calculated with the convergent close-coupling (CCC) method from the a…
Calculation of the free-free transitions in the electron-hydrogen scattering S-wave model
Chris Plottke, Igor Bray
The S-wave model of electron-hydrogen scattering is evaluated using the convergent close-coupling method with an emphasis on scattering from excited states including an initial sta…
