The energy difference between an uncharged species and its negative ion, referred to as an
electron affinity (EA), is an important property of atoms and molecules. Negative ions, or …

The authors attempt to give a comprehensive discussion of observations of atomic negative-
ion resonances throughout the periodic table. A review of experimental and theoretical …

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 …

In characterizing anion states either experimentally or theoretically different techniques are
required for bound and temporary or metastable anions. Anions that lie energetically above …

Theoretical and experimental methods for studying electron attachment to molecules in the
range 10's of eV to several μeV are reviewed. Theoretial methods include use of the …

There have appeared a series of excellent reviews dealing with various aspects of anion
chemistry during the last decade. Although most of these articles deal with experimental …

We present experimental evidence for the existence of a stable Ca− ion formed in the bound
(4 s 2 4p) 2 P state. This result represents the first report of a stable negative ion for a group …

The atomic electron affinities of the eight first row (H, Li,…, F) atoms as well as the adiabatic
electron affinities of 12 first row diatomic and 15 first row triatomic molecules were …

Abstract Multiconfiguration Hartree-Fock theory and density-functional theory both show that
the negative ions Ca− and Sc− have stable ground states, the extra electron being a 4p …

2014 This paper presents an introductory overview of various aspects of electron
detachment from negative ions with emphasis on recent data. A brief discussion about …
