Observation ofNe+toNe8+Kx rays followingO5,6,7,8+bombardment

The Ne $K$ x-ray spectrum following bombardment by 30-MeV ${\mathrm{O}}^{5+}$ and 35-MeV ${\mathrm{O}}^{6+}$, ${\mathrm{O}}^{7+}$, and ${\mathrm{O}}^{8+}$ beams has been resolved into nine lines corresponding to $K{L}^0$ through $K{L}^7$ transitions. Using a curved-crystal spectrometer, relative intensities for the previously unresolved $K{L}^0$, $K{L}^1$ and $K{L}^2$ transitions have been extracted despite the overlap of the H-like oxygen-beam x rays. For ${\mathrm{O}}^{5+}$ and ${\mathrm{O}}^{7+}$ bombardment, the measured relative intensities of the remaining lines disagree with a previous measurement.
