Abstract:
A new crossed beam instrument for the study of ion-molecule collision processes is described. During the development work a novel method of focussing an ion beam from a quadrupole mass filter was devised. Using an electrostatic octopole lens it is possible to obtain low energy ion beams with narrow energy distributions and with intensities and angular distributions close to the fundamental space charge limit. The aim of this work has been to investigate the dynamics of the reactions of diatomic ions with diatomic molecules. The results of a detailed study of the reactions CO+ + O2 = CO+2 + O CO+ + NO = CO+2 + N CO+ + NO = (NCO)+ + O are presented and discussed. All the reactions were found to proceed by a direct mechanism over the energy range studied although there is substantial evidence for the coupling of the motion of all atoms in reactive collisions. At high energy the total cross sections decline as the dynamics become dominated by product stability restrictions and there is evidence for the formation of electronically excited product.
