Comparison of the main parameters of the ion-photon emission of titanium atoms and singly charged ions

Abstract

The emission spectra of titanium particles (TiI and TiII) sputtered during Ar⁺-ion bombardment of a titanium surface are investigated. The experimental dependences of the efficiency of Ti atom and ion excitation on the excited-state energy are determined. For the TiI and TiII spectral lines, the spatial distribution of radiation is studied and the kinetic energy of particles flying off the surface is determined. These data are used to make assumptions about processes occurring in the system under consideration.
