We have observed optical spectra of beryllium, carbon, and aluminum atoms and ions from particles ejected from foils by impact of uranium ions. The ejected particles responsible for the spectra had energies of the order of 10 keV; neutral and singly ionized species were predominant. This method of producing spectra may be useful in the extension of standard beam-foil techniques and for spectrochemical analyses of microgram quantities of certain materials.

Observed wavelengths are vacuum values taken from the wavelength dial of the spectrometer and are subject to approximately ±1 Å systematic error in addition to reading uncertainty of outputs, typically ±1 Å.
Lines marked (K) have total intensity 500 or higher in R. L. Kelly, Atomic Emission Lines Below 2000 Angstroms, NRL Report 6648 (U. S. Govt. Printing Office, Washington, D. C., 1968). Lines marked (S) have total intensity of 10 or higher in A. R. Striganov and N. S. Sventitskii, Tables of Spectral Lines of Neutral and Ionized Atoms (Plenum, New York, 1968). Beryllium lines above 2000 Å were checked against G. R. Harrison, M.I.T. Wavelength Tables (Wiley, New York, 1960).
