Journal Article

Journal ArticleDOI

TL;DR: In this paper, a method is developed that describes resonant nuclear scattering from which centroids and widths in the compound nucleus are obtained when one of the interacting bodies has particle unstable resonances.
Journal ArticleDOI
Polarization of Balmer-α radiation following electron impact on atomic hydrogen
TL;DR: In this article, the polarization of Balmer-α radiation excited in collisions of electrons with atomic hydrogen is presented for an electron energy range from threshold to 1000 eV, in good agreement with calculations carried out using either convergent-close-coupling or R-matrix with pseudo-state approaches.
Journal ArticleDOI
Almost sudden perturbation of a quantum system with ultrashort electric pulses
A. V. Lugovskoy,Igor Bray +1 more
TL;DR: In this article, an alternative approach to analyze atomic behavior when an external field perturbation is not sudden for a number of states of the field-free system is presented. But the approach is limited to one-dimensional Coulomb potentials.
Journal ArticleDOI
Antihydrogen formation in low-energy antiproton collisions with excited-state positronium atoms
TL;DR: In this article, the convergent close-coupling method is used to obtain cross sections for antihydrogen formation in low-energy antiproton collisions with positronium (Ps) atoms in specified initial excited states with principal quantum numbers ≤ 5.
