Abstract

The application of two-dimensional imaging and storage ring techniques to analyze the breakup dynamics of D₂H⁺ and H ₂D⁺ following dissociative recombination with low energetic electrons, was investigated. The correlation between the hydrogen and deuterium atoms produced in the three-body channel were calculated. It was observed that the deuterium atom has a large probability at the center and the three particle tend to dissociate with geometry close to linear. The results show that the remaining average internal excitation energy stored in the rotation of the molecules corresponds to a temperature of less than 70 meV.
