【 摘 要 】

Dissociation of doubly charged Anthracene was studied in collisions with a fast 3 keV F+ion beam. From fragmentation mass spectrum measured in coincidence with the energy deposited in the molecule, we have determined the dissociation rate for the loss of C2H2and H as a function of energy. The cooling of singly charged Anthracene was studied using a small electrostatic storage ring. The fluorescence emission rate has been determined and compared with a theoretical model.
