Abstract

Dielectronic recombination was investigated for He+, the simplest ion for which this process is possible. This work was done using the light-ion storage ring and electron cooler at the Indiana University Cyclotron Facility. Resonant recombination yields resulting from 1s +e- --> nln'l' transitions were observed with sufficient resolution (about 1 eV in the center of mass) to isolate and obtain cross sections for the 2s 2p 3P0 and 2p2 1D terms. The measured cross sections, integrated over the DELTAn = 1 2ln'l' states, agree in magnitude with theoretical calculations. Additionally, DELTAn = 2 dielectronic recombination events associated with 3ln'l' intermediate states were observed.
