Optical model for positronium formation in e+-Na collision
Description
The optical-model approach has been used to investigate positronium (Ps) formation in e+-Na collision at low impact energies (0.1-20.0 eV). A complex equivalent local polarization potential is obtained to describe the rearrangement process. The Ps formation cross section is excellently reproduced by this potential. The results for the Ps (n=1) and Ps (n=2) formation cross sections are reported and compared with the experimental measurements and other close-coupling calculations
