Total (elastic + rotationally inelastic) integral cross sections are computed
for O2(3Σg−)-O2(3Σg−) using a recent ab initio potential
energy surface. The sampled velocity range allows us a thorough comparison of
the glory interference pattern observed in molecular beam experiments. The
computed cross sections are about 10% smaller than the measured ones, however,
a remarkable agreement in the velocity positions of the glory extrema is
achieved. By comparing with models where the anisotropy of the interaction is
reduced or removed, it is found that the glory pattern is very sensitive to the
anisotropy, especially the positions of the glory extrema.Comment: 13 pages, 3 figure
