摘要：

We present the first measurements of visible radiation from W10+. The ions are produced and confined in an electron-beam ion trap (EBIT) at Shanghai EBIT Laboratory, and the spectra are recorded with a Czerny-Turner spectrometer in the wavelength range 30 0-70 0 nm. The observed five new spectral lines are identified using detailed collisional-radiative (CR) modeling of the EBIT spectra. In addition, we perform large-scale theoretical calculations for the lowest 50 energy levels of W 10 + using FAC and GRASP codes. The excitation energies obtained by the two independent calculations fit well with each other, with-0.5% difference on average, and the resulting values are adopted to check our line identifications, with wavelength deviations from experimental results-1.5% on average.
