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.展开更多

Highly charged H-, He-, Li-, and Be-like ions were obtained after the foils. The excitation spectra and level lifetimes for these ions were measured, and transition configurations for most measured lines were identified展开更多

Spectral lines emitted from fifty- three excited energy levels were observed in the wavelength range 120—220 ?, among which eleven lines were new. Our experimental results show good agreement with the results of laser plasma experiments, and are in reasonable agreement with theoretical calculations.展开更多
