Abstract
We report detailed results for positron-H-2 collisions obtained with the
Schwinger multichannel method. Our calculations include annihilation
parameter, differential, integral, and momentum transfer cross sections
for energies below the positronium formation threshold. The calculations
were carried out in the static-plus-polarization approximation with
symmetry-resolved cross sections. Energy (temperature) dependence and
symmetry-resolved contributions for the annihilation parameter Z(eff)
are also reported. Our ab initio integral cross sections are found to be
in good agreement with the experimental data. S1050-2947(98)04409-6.
