Extensive theoretical and experimental studies have been carried out for the past 20 years
on electron-ion recombination processes, as they are applied to the analysis of …

Abstract The Antiproton Decelerator (AD) facility of CERN began operation in 1999 to serve
experiments for studies of CPT invariance by precision laser and microwave spectroscopy of …

The dissociative recombination of an H 3+ ion after it is struck by a low-energy electron is
important for understanding observations of H 3+ in diffuse interstellar clouds. At the same …

Energies and absolute cross sections for dielectronic recombination of lithiumlike Cu 2 6+
via ΔN= 0 and ΔN= 1 resonances have been measured at the Heidelberg heavy-ion storage …

Knowledge of the abundance of H3+ is needed in interstellar and planetary atmospheric
chemistry. An important destruction mechanism of H3+ is low-energy electron impact …

Absolute cross sections have been determined for the dissociative recombination and
dissociative excitation of HeH+ 4 for electron energies below 40 eV. The dissociative …

The low-energy C IV dielectronic recombination (DR) rate coefficient associated with 2s→
2p Δ n= 0 excitations of this lithium-like ion has been measured with high-energy resolution …

We have measured the dielectronic recombination cross section of Se 2 5+ ions at center-of-
mass energies from 1 to 1800 eV using merged electron and ion beams in the Heidelberg …

Atoms and molecules make up a large fraction of the interstellar medium (ISM) and other
astrophysical environments. Understanding how they are formed, destroyed, and altered via …

Cold antihydrogen atoms were produced by mixing cold samples of antiprotons and
positrons. The temperature of the positron plasma was increased by controlled radio …
