In view of the current interest in trapping antihydrogen H(bar sign) atoms below 1 K, the s-wave elastic-scattering parameters for the antihydrogen scattering off atomic helium target are calculated in the energy range 1x10{sup -16}-1x10{sup -2} a.u. using close-coupling models. The predicted cross section will help to simulate the evolution of a realistic mixture of He and H{sub 2} through the process involving ejection of H(bar sign) from the trap. The trend of the present results with different basis sets conclusively indicates the reliability of the predicted results.
