Abstract
We investigate the recombination of the HCO+ ion on grain surfaces. This process is a key reaction in dense regions such as protoplanetary disks. The branching fraction among intact desorption, dissociation, and desorption with dissociation has been analyzed by a classical trajectory approach. It is found that dissociation (with or without desorption) dominates over intact desorption.Keywords
