The article shows the fundamental possibility of using the bombardment of the surface of solids by kilo V ions for exciting the emission spectrum of particles of the target material and for obtaining spectroscopic data. The method is tested by studying the emission spectra of holmium as an example. It is shown that the sensitivity of the method can be substantially increased by using the so-called chemical effect, i.e., the effect of strengthening the spectral lines of sputtered excited metal atoms during bombardment of the target in the presence of oxygen. It is proposed that the chemical effect, which takes place only for atomic lines, in contrast to ionic ones, can also be used for simplifying the identification of atomic lines. It is noted that the proposed method is suitable for studying the atomic spectra of any solids, including refractory and chemically reactive substances.
