Abstract
In this paper, we describe calculations that we have carried out of cross sections for rearrangement processes in very low-energy helium + antihydrogen (H¯) scattering that result in He+p¯+Ps or Hep¯+e+ or αp¯+Ps-. A significantly more accurate method from that used previously [E.A.G. Armour, S. Jonsell, Y. Liu, A.C. Todd, Nucl. Instr. and Meth. B 247 (2006) 127] is used to calculate the He+H¯ entrance channel wave function. Results are presented for the first two processes. Mention is made of the use of the method in calculations of low-energy e+H2e+H2 scattering.
