Abstract
The author has confirmed the existence of a resonance shape around 35.6 eV, previously found by Higgins and Burke (1991) in the S-wave positronium formation cross sections that has been calculated also within the coupled-static approximation but with the use of the Harris-Nesbet variational method. Still within the spirit of the coupled-static approximation, the author added the polarization effects to the process of including the pseudo-state 2p in the coupling scheme, and found a whole range of structures formed at this intermediate energy region of the positronium formation cross sections. These structures were also seen in the elastic cross sections. The author discussed the formation of these structures.Keywords
