Show affiliationsThe Lippmann-Schwinger (LS) equation for the K matrix is numerically solved for the collision of H+2 + e interacting by the configuration interaction (CI), of which magnitude is carefully deduced from ab-initio calculation of electron scattering. The LS equation is extended to the negative collision energies in the context of multichannel quantum defect theory (MQDT) for the dissociative recombination (DR). Using the MQDT method for the DR, The DR cross section of H+2 is obtained. It has turned out that the DR at low energy is induced by the indirect process with rotational excitation and the off-the-energy-shell contribution is indispensable for the accurate description. The present calculation represents the recent state specific experiment [1], and has assured the effectiveness of the MQDT method for DR.
