The electron-sodium system is an excellent prototype of non-relativistic electron scattering from a quasi-one-electron atomic target, and is tractable both experimentally and theoretically. Recently, this system has been studied in a series of
Using a fixed frequency argon ion laser, we have studied the energy spectra of electron photodetached from OH -, NH 2 -, NH -, SO 2 -, and S 2 -. We determined the following electron affinities: E A(OH) = 1.829 +0.010 -0.014 eV, E A(NH 2) = 0.779plus or
