✦ Synopsis


The effect on the H+Hs reaction of the geometric phase induced by the conical intersection between the two lowest electronic states of H, is investigated by an accurate quantum mechanical computation up to 2.6 eV above the bottom of the ground state HZ electronic potential well for the total angular momentum J=O. The main effects of the inclusion of the geometric phase are a sign change in the reactive scattering matrix and modifications in the nuclear permutation symmetries of the calculated resonances. Cross-sections to which non-reactive processes contribute (ortho+ortho and para+para) are significantly modified, whereas the others (ortho-para and para+ortbo) are not.
