摘要：

Present computations refer to the dissociative recombination and excitation of H-2(+), HD+ and HT+ with electrons of energy above the dissociation limit of the ground state. A wave packet discretization method is used to describe the vibrational continua of the electronic states of the molecular cations. Assuming the energy-independent electronic interactions, this nonrotational MQDT approach is based on a second-order Born expansion of the reaction matrix. (C) 2009 Elsevier B.V.
