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 …

A simple analytic formula for the photodetachment cross section of H− in an electric field is
derived. The formula becomes identical to a formula derived many years ago in the …

The negative ion of hydrogen continues to be important in atomic physics and astrophysics.
Correlations between the two electrons are strong already in the ground state, the only …

Outgoing electron waves produced in the photodetachment of H− are propagated to large
distances in a homogeneous electric field, and the electron flux is then computed. It is shown …

This paper provides a general theoretical description of a weakly bound atomic system (a
negative ion) interacting simultaneously with two (generally strong) fields, a static electric …

In this paper we obtain a simple analytic formula for the photodetachment cross section of
H− in parallel electric and magnetic fields. The three-dimensional semiclassical …

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 …

Simple analytic formulas are presented for the photodetachment cross section of H− in the
presence of parallel electric and magnetic fields. A rich array of photodetachment spectra …

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 …
