Abstract

We report Doppler-free spectroscopy of neutral europium carried out using the saturation absorption technique. In the present experiment, Eu/Ne hollow cathode discharge is used as an atomic vapor source of europium. The Eu transition 4f76s2(S87/2°)→4f76s6p(P89/2) at 601.815 nm and 4f75d6s(aD1013/2°)→4f75d6p(zD811/2) at 580.027 nm are investigated. The frequency separation between the adjacent hyperfine transitions as well as hyperfine structure (HFS) constants are calculated from the obtained experimental spectra. The HFS constant obtained for the state 4f76s6p(P89/2) are A151=664.8  MHz; B151=293.5  MHz, and for state 4f75d6p(zD811/2), the values are A151=7.6  MHz; B151=-60  MHz. These obtained values are in good agreement with the results reported in the literature using laser induced atomic beam fluorescence technique.

Europium Bohr ModelThe number of electrons in each of Europium's shells is 2, 8, 18, 25, 8, 2 and its electron configuration is [Xe]4f7 6s2. The europium atom has an atomic radius of 180 pm and a Van der Waals radius of 233 pm. Europium was discovered by Eugène-Anatole Demarçay in 1896, however, he did not isolate it until 1901. Europium was named after the continent of Europe.Elemental Europium Picture Europium is a member of the lanthanide or rare earth series of metals. In its elemental form, it has a silvery-white appearance but it is rarely found without oxide discoloration. Europium is found in many minerals including bastnasite, monazite, xenotime and loparite. It is not found in nature as a free element.
