In this paper we summarize our preliminary results for dissociative recombination for a model molecular hydrogen cation system. The recombination cross sections are calculated by two different approaches.
The first method solves the model two-dimensional Hamiltonian in a numerically exact manner. These results are considered as reference data for the second, approximate approach that is more suitable for real molecular applications: the method of frame transformation into the basis of Siegert states representing nuclear degrees of freedom.
