Low-energy electron scattering from Mg, Zn, Cd and Hg: shape resonances and electron affinities

Abstract
Measurements of electron scattering at low energy from Mg, Zn, Cd and Hg have been carried out using the electron transmission method. A large shape resonance is observed for each element which is identified with the (ns2np)2P ground state of the negative ion. The electron affinities in eV are found to be Mg(-0.15), Zn(-0.49), Cd(-0.33) and Hg(-0.63) with an error of +or-0.04 eV. The results are compared with the available theoretical predictions.
