Abstract

Extreme ultraviolet spectra of highly-charged ytterbium ions produced in an electron beam ion trap at National Institute of Standards and Technology were observed with a at- eld grazing incidence spectrometer in the wavelength region of about 4 nm to 20 nm. The measured spectra were interpreted through detailed analysis by collisional-radiative modeling of the non-Maxwellian EBIT plasma. Seventy-nine new spectral lines due to intrashell (
n = 0, n = 4) electric-dipole, magnetic-dipole and electric-quadrupole transitions were identi ed in Rb-like Yb33+ through Ni-like Yb42+ ions. The e ects of strong con guration interaction within the n=4 complex on the measured spectra are discussed for a number of ionization stages.
