| Abstract: | ![]()
The analytical independent-particle model of Berg, Purcell, and Green (BPG) is extended to describe low-energy scattering of electrons by the argon atom. The Ramsauer-Townsend minimum and the scattering length are only well reproduced when the BPG model is supplemented with a polarization potential as proposed by Sandhas.Dedicated to Prof. Werner Sandhas on the occasion of his 60th birthday |
