Recent progress in the study of positronpositron and positroniumpositronium induced
ionizationionization is reviewed within the context of the inert atoms. The focus is on …

The question of convergence in two-center close-coupling expansions is addressed via the
study of positron-hydrogen scattering. It is found that the major cross sections do converge if …

We present a critical analysis of available experimental and theoretical cross section data for
positron scattering from atomic systems. From this analysis, we present (where data are …

The first absolute experimental determinations of the differential cross sections for the
formation of ground-state positronium are presented for He, Ar, H 2, and CO 2 near 0° …

Due to the dominant electron capture by positrons from the molecular shell and the spatial
dephasing across the shell width, a powerful diffraction effect universally underlies the …

The recent theoretical work by Bartlett et al. J. Phys. B 38, L95 (2005) and the latest
measurements on the reduced Stokes parameters P_1, P_2 and P_3 for 54.4 eV electron …

We previously predicted [PA Hervieux, Phys. Rev. A 95, 020701 (R)(2017) 2469-9926
10.1103/PhysRevA. 95.020701] that, owing to predominant electron capture by incoming …

The application of an exterior complex scaling method to an atomic scattering problem with
distinct rearrangement channels is reported. Calculations are performed for positron …

The fundamental three-body Coulomb system has been intractable. Nonetheless, there
were quantum leaps in this research field over the last 3 decades, especially in the simplest …

Positron scattering by hydrogen atom is an interesting system to test theoretical methods
due to its simplicity. Recently, theoretical calculations have reported differential cross …
