This paper reviews the knowledge of the structure, dynamics and collisions of atomic
negative ions, as accumulated at the end of 2003, and describes how the research exploring …

This review focuses on the use of accelerator-based methods to investigate the interaction
between negative ions and photons, electrons, heavy particles and external electric fields …

Photodetachment microscopy has been performed on a beam of 32S-ions. Analysing the
electron images obtained, we find that the electron affinity measurements performed with the …

Standard closed-orbit theory is applied to derive the photodetachment cross section of H− in
the presence of a static electric field. The result agrees with the one derived earlier using a …

We study the photodetachment cross sections of H− near a metal surface using closed-orbit
theory. Formulas for cross sections are presented. We find the metal surface mainly modifies …

Negative ions undergoing near-threshold photodetachment in a weak laser field provide an
almost pointlike, isotropic source of low-energy electrons. External fields exert forces on the …

K-shell photodetachment from C− has been investigated in the photon energy range
between 280 and 285 eV using the merged ion-beam–photon-beam technique. C− ions …

We examine the spatial distribution of electrons generated by a fixed energy point source in
uniform, parallel electric, and magnetic fields. This problem is simple enough to permit …

An alternative description of quantum scattering processes rests on inhomogeneous terms
amended to the Schrödinger equation. We detail the structure of sources that give rise to …

Localized scattering phenomena may result in the formation of stationary matter waves
originating from a compact region in physical space. Mathematically, such waves are …
