TL;DR: In this article, electron emission from single-electron capture with simultaneous single ionization in 30 keV/u He${}^{2+}$ on argon was investigated using a reaction microscope, providing the electron energy spectra and momentum distributions.

TL;DR: In this paper, the kinetic energy distributions of the fragment ions of doubly and quadruply ionized argon dimers were measured using 3000 eV electron impact and the peak that indicates radiative charge transfer was observed.

TL;DR: In this article, the authors analyzed the correlation between different fragmentation mechanisms and the kinetic energy release (KER) and found that the sequential process occurs with higher KER while, in contrast, the concerted process mainly contributes to the lower KER.

TL;DR: In this paper, the authors analyzed the momentum distribution and kinetic energies of the three fragment ions, and verified the nonsequential and sequential dissociation mechanisms of the fragment ions by analyzing their kinetic energies.

TL;DR: In this article, the authors used rubidium atoms with specified mass and internal energy to carry out a joint mass-energy test of the equivalence principle (EP), and they used the extended 4WDR to select atoms with a certain mass and angular momentum state, and form a dual-species atom interferometer.
