Section: Dissociative recombination (DR)

Geppert, ....

1. Introduction

• Short overview over electron-ion recombination processes
  (What makes DR especially feasible for astronomic environments)
• Mechanisms of DR (direct, indirect)
• Relevance of DR processes in different astronomical objects(dark and diffuse clouds, circumstellar envelopes, planetary ionospheres, cometary comae)
• Other non-astrochemical environments where DR plays a role

2. Experimental methods to investigate DR reactions –merits and pitfalls

(Possible co-authors: Wolf, Glosik, Johnsen)

• Afterglow methods
• Storage ring methods
• Other techniques
• Future experimental device (CSR etc.)

3. Ab initio calculations of DR reactions

(Possible co-authors: Orel, Guberman, Talbi)

• State of the art methods
• Influence of rovibrational excitation on DR
• Role of resonances
• Some astrochemically interesting examples (H₃⁺, N₂H⁺, HCO⁺)

4. Summary and conclusions
