Two-center convergent-close-coupling calculations for positron-sodium collisions
Positron scattering from sodium atoms has been studied theoretically with the use of the two-center convergentclose-coupling method. The target has been treated in the framework of a one-active-electron approach. The positronium formation channels are taken into account explicitly utilizing Laguerre...

| description | Positron scattering from sodium atoms has been studied theoretically with the use of the two-center convergentclose-coupling method. The target has been treated in the framework of a one-active-electron approach. The positronium formation channels are taken into account explicitly utilizing Laguerre-based states. Our calculations are overall in good agreement with the previous theoretical results, and so the discrepancy with experiment at low energies remains unresolved. |
