摘要：

In this paper, we describe calculations that we have carried out of cross sections for rearrangement processes in very low-energy helium + antihydrogen ((H) over bar) scattering that result in He(+)p + Ps or Hep + e(+) or alpha p + 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) over bar 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(+)H(2) scattering. (c) 2008 Published by Elsevier B.V.
