TL;DR: In this article, the authors report triply differential measurements of atomic hydrogen ionization by 17.6-eV electrons, with the outgoing electrons both having 2 eV energy, and the complete set is critically analyzed and is found to be much more internally consistent than before, thereby providing one of the most stringent tests for theory.

TL;DR: In this article, eigenphase sums and partial cross sections for elastic scattering and electron-impact excitation of the n = 2 states of atomic hydrogen were obtained by using convergent close-coupling (CCC), R-matrix with pseudo-states (RMPS), and intermediate-energy Rmatrix (IERM) methods.

TL;DR: In this article, a coupled channel optical method for electron-char21{}atomic-hydrogen scattering is presented in a form that treats both the projectile and the target electrons symmetrically.

TL;DR: The authors have predicted the quantum suppression of the cross-section for antihydrogen formation in positronium scattering with antiprotons, by including the excited states and using convergent close-coupling calculations.

TL;DR: In this paper, a joint experimental and theoretical investigation of electron-impact excitation of the 5d 10 6s 2 S1/2 →5d 106p 2 P 1/2,3/2 resonance transitions in gold atoms is presented.
