Abstract :
We present results for low-energy elastic S-, P-, and D-wave phase shifts, capture and total cross sections of positron-helium scattering with different basis sets in the close coupling approach using realistic wave functions for He(1s1s), He(1s21s), He(1s21p) and positronium (1s) states. A resonance is found in the S-wave capture cross section at 84 eV.
