Abstract 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 $\pm$ 0.03nm. 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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
