Isotope shift studies in the spectral lines of Yb I in the 340-436 nm region and term shifts of some odd- and even-parity energy levels

A detailed and up-to-date analysis of the first spectrum of ytterbium (Yb I) was published which provided wavelengths and estimated intensities of 1791 lines of Yb I and they could classify 787 lines of Yb I as transitions between 102 even- and 77 odd-parity levels. The present study was undertaken to measure the isotope shifts in the UV lines of Yb I and evaluate the term isotope shifts, ΔT (172Yb - 176Yb), of the energy levels of Yb I and correlate these ΔT values with the assigned electronic configurations of these levels
