Experimental study of highly ionized spectra of titanium

The spectra of highly charged titanium ions produced by the interaction of 120 MeV titanium ions with carbon foil were investigated with the so-called beam-foil technique using the HI-13 tandem accelerator in China Institute of Atomic Energy. Spectral lines emitted from fifty-three excited energy levels were observed in the wavelength range 120–220 A, 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.
