- Аннотация: The energy spectra of secondary ions 63Cu+, emitted from the (100) face of Cu single crystal in the close-packed <110> directions, as well as between them, have been studied and shown to be differ, both in shape and position, depending on the temperature of the target. We have established that, if a sample has not been heated, the most probable energy of the ions (Еmax) and the width (h) of energy spectra increase with the growth of the polar angle q of emission. However, for a sample heated to several hundred degrees Celsius the opposite behavior have been obtained, i.e. Еmax decreases with the growth of q. We discuss the observed trends which need to be taken into account, both when describing the process theoretically, and when applying it to practical use in mass-spectrometry of secondary ions.
