TY - JOUR TI - Optical potential approach to the slow positron scattering from helium atom AU - Tančić Aleksandar R. AU - Nikolić M.R. JN - Facta universitatis - series: Physics, Chemistry and Technology PY - 2002 VL - 2 IS - 4 SP - 183 EP - 188 PT- Article AB- We have extended our previous calculations to include the contribution of the random-phase approximation (RPA) (improved) optical potential to the low energy elastic scattering in the electron+He system. Our improved RPA calculations are shown to be in better agreement with the experimental values than other theoretical results.
