Title: Effective configurations in positron-molecule scattering
Author: Varella, MTD
Azevedo, DL
Lima, MAP
Abstract: In this work, we extend the effective configurations (EC) approach (Azevedo D L, da Silva A J R and Lima M A 2000 Phys. Rev. A 61042702) to positron scattering. EC are pseudo-eigenstates of the (N+1)-body collision Hamiltonian. They provide a much more efficient description of polarization effects in scattering calculations by allowing considerable contraction of configuration spaces. As a result, significant computational time is saved.
