,Positive-Ion—Molecule Reaction Studies in a Single Electron-Impact Source, along the path of the electron beam. A small, positive potential is normally applied to the repeller and causes the ions to drift toward the exit slit and into the ion gun and the analyzer. A typical source is shown in Fig. 1. Under ordinary operating conditions, the pressure in the ion source is o

Ion-Molecule Reactions by Photoionization Techniques,veral years photoionization techniques have been applied to this area of research. The experimental techniques of photoionization are generally more difficult to apply than those of electron impact, but have certain strong advantages in the ability to provide more precisely characterized preparation

,Higher-Order Reactions—Ion Clusters and Ion Solvation,t pressures above 1 Torr. Many of the phenomena encountered in this pressure range have significance beyond the study of ion clusters. Some such features of general importance to ion-molecule reactions at elevated pressures are also included in the discussion.
