摘要: We have observed resonance structures in detached electron spectra arising from fast collisions of Li− with gas targets and photo-detachment Li−. Using a generalization the Wigner threshold law, we were able to fit experimental data high degree accuracy. Moreover, extract numerical values different electron-atom parameters as scattering length, effective range potential number supported bound states. Results for length obtained this two differentiated experiments agree each other within maximum error 2%.
