Dielectronic recombination has been investigated for ground-state Li{sup +}(1s{sup 2}) and metastable Li{sup +}(1s2s) ions. Absolute recombination rates for the convoluted sum of these configurations are obtained and compared with theoretical calcula

Dielectronic recombination (DR) was investigated for Li + + e − collisions using the electron cooler at the Indiana University Cyclotron Facility (IUCF). For Li + (1s 2 ) ions, DR is expected to occur for relative energies E rel between 50–60 eV,

Knowledge of the abundance of H(3)(+) is needed in interstellar and planetary atmospheric chemistry. An important destruction mechanism of H(3)(+) is low-energy electron impact followed by dissociation, but estimates of the reaction rate span several

Ion storage rings offer several advantages for studies of recombination of molecular ions by electrons, a process which in general leads to dissociation. During the last year dissociative recombination of H+3, HD+, H+2, 3HeH+, 4HeH+, and 4HeD+ have b
