摘要：

We consider the low-energy scattering of antihydrogen ((H) over bar) by the simplest molecule, H(2). This preliminary treatment applies a generalisation of the Kohn variational method to the calculation of total elastic cross section at low energies. The scattering wavefunction calculated by the generalised Kohn method is used to estimate the antiproton annihilation in flight using a delta function pseudo potential introduced in the treatment of antiproton annihilation in H-(H) over bar scattering.
