Mueller (Strahlenzentrum der Universitaet Giessen), W. G. Graham (Queen’s University, Belfast), A. D. Price, N. R. Badnell (University of Strathclyde), T. W. Gorczyca | | Abstract: | Dielectronic recombination has been investigated for Delta-n = 1 resonances of ground-state Li+(1s^2) and for Delta-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 2 ^3S level of Li+. | | Source: | arXiv, physics/9907030 | | Services: | Forum | Review | PDF | Favorites | |
