Introduction,stigation it was considered that the bombarding atomic particle caused the emission of secondary ions, neutral atoms (cathodic sputtering), and electrons. This simplified picture of the phenomena is illustrated in Fig. 1.

Dynamic (Oscillographic) Method of Investigation,target surface is required to remain clean, yet at the same time measuring the energy distribution of the secondary particles by the static method, i.e., taking one volt—ampere characteristic, is a long process, requiring several hours or more, and it is almost impossible to keep the surface clean f

Angular Relationships of Secondary Ion Emission,ngular distribution of the scattered particles and the angular dependence of the energy spectra. There have been a number of investigations into the angular distribution of scattered ions and atoms in gas targets. At the same time, the distribution of ions sca
