Abstract

Dielectronic recombination has been investigated for -n=1 resonances of ground-state Li+(1s2) and for -n=0 resonances of metastable Li+(1s2s 3S). The ground-state spectrum shows three prominent transitions between 53 and 64 eV, while the metastable spectrum exhibits many transitions with energies <3.2 eV. Reasonably good agreement of R-matrix, LS coupling calculations with the measured recombination rate coefficient is obtained. The time dependence of the recombination rate yields a radiative lifetime of 52.2±5.0 s for the 23S level of Li+.
