Resumen:
We have observed resonance structures in detached electron spectra arising fromfast collisions of Li- with gas targets and from photo-detachment of Li-. Using a generalizationof the Wigner threshold law, we were able to fit the experimental data to a high degreeof accuracy. Moreover, we were able to extract numerical values of different electron-atomparameters as the scattering length, the effective range of the potential and the number ofsupported bound states. Results for the scattering length obtained from this two differentiatedexperiments agree with each other within a maximum error of 2%.
