Intercombination lines of the zinc isoelectronic sequence for Z = 50<i>–</i>70

Abstract

The intercombination lines of the zinc sequence corresponding to the transition 4s4p ${}^{3}$${P}_{1}$\ensuremath{\rightarrow}4${s}^{2}$ ${}^{1}$${S}_{0}$ have been observed for xenon, lanthanum, neodymium, europium, gadolinium, and ytterbium in the Princeton Large Torus tokamak discharges.
