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(Isis), He(ls21s), He(ls21 p) and positronium (ls) states. A resonan
We study positron-helium scattering using close coupling approximation (CCA) employing different combinations of the following basis functions: He(Isis), He(ls2s), He(ls2p), Ps(ls), and Ps(2s), where Ps stands for the positronium atom. We observe a prominent S wave resonance of width 2 eV at about 3
