Abstract

We report the observation of new high-lying even-parity excited levels of samarium in the energy region $34814.4{\mathrm{cm}}^{-1}\text{to}35110.9{\mathrm{cm}}^{-1}$. These levels are identified with two-color laser-induced fluorescence spectroscopy in an atomic beam. The values of the total angular momentum $\left(J\right)$ of these levels are assigned. Our results are compared with the results obtained with two-color, three-photon photoionization spectroscopy in the same energy region reported earlier in the literature [J. Opt. Soc. Am. B 13, 641 (1996) ]. The similarities and differences observed in the spectra by two techniques have been discussed, reaffirming the complementary nature of the two techniques for laser spectroscopy of highly excited levels.
