| 摘 要： | The foil-excited the spectrum of highly stripped titanium ions between 12-40 nm has been studied. Titanium ions of 80 and 120 MeV were provided by the HI-13 tandem accelerator at the China Institute of Atomic Energy. GIM-957 XUV-VUV monochromator was refocused to get highly-resolved spectra. Our experimental results and the published spectral data of laser-produced plasma show agreement in nearly all cases within ±0.03 nm. The spectra contained some weak or strong lines previously unclassified. These spectral lines mainly belong to 2s2p^2 for TiXVⅢ, 2p^3 for TiXVIII, 2s2p^3 for TiXVII, 2p^6 4p for Ti XII and 2p^6 3d for Ti XII transitions.

| Abstract: | The foil-excited the spectrum of highly stripped titanium ions between12--40~nm has been studied. Titanium ions of 80 and 120~MeV were provided by theHI-13 tandem accelerator at the China Institute of Atomic Energy. GIM-957XUV-VUV monochromator was refocused to get highly-resolved spectra. Ourexperimental results and the published spectral data of laser-producedplasma show agreement in nearly all cases within pm 0.03nm.The spectra contained some weak or strong lines previouslyunclassified. These spectral lines mainly belong to 2s2p^{2 } for TiXVIII,2p^{3} for TiXVIII, 2s2p^{3} for TiXVII, 2p^{6}4p for Ti XIIand 2p^{6}3d for Ti XII transitions. |
