Abstract
We have observed resonance structures in detached electron spectra ari sing from fast collisions of Li- and ions with gas targets. The struct ures are associated with the autodetaching decay of shape resonance st ates. Using Shore parametrization, we obtain resonance energies and wi dths of 50(6) and 64(25) meV, respectively, for the Li-(2s2p(3)P) stat e and 104(8) and 68(25) meV, respectively, for the tentatively identif ied B-(2p(21)D) state. Other resonances in B- remain unidentified.
