Research on EUV spectra of highly ionized titanium

The spectrum of highly ionized titanium was studied by means of the beam-foil technique. Titanium ions were provided by the HI-13 tandem accelerator at China Institute of Atomic Energy. The experimental results are compared with those of laser-produced plasmas. Numerous lines attributed to Ti XVI to XVIII ransitions have been identified, and three of them were newly measured, which were attributed to 2s2p(24)P(3/2)-2p(32)D(3/2), 2s2p(21)S(0)-2sp(31)P(1) and 4p(1)P(0)-5d(1)P(1) transitions.
