Abstract

Charge-resolved extreme ultraviolet spectra of open N-shell neodymium (Nd) ions have been recorded in an electron beam ion trap facility at the National Institute of Standards and Technology. The measurements have been performed for nominal electron beam energies in the range of 0.90 keV to 2.31 keV. The measured spectra have been compared with the spectra simulated by a collisional-radiative model based on atomic data produced with a fully relativistic atomic structure code. Consequently, 59 lines from Br-like to Ni-like Nd ions have been unambiguously identi ed, most of which are newly assigned in this study. The wavelengths of 9 known lines from Ni-, Cu- and Zn-like Nd ions were in excellent agreement with the previous measurements.
