Abstract

Systematic mapping of high-lying even-parity levels (low-lying configurations) of the samarium atom below the first ionization potential was carried out with a two-step photoexcitation and photoionization method. Five hundred seventy-one new energy levels were discovered in the region 34 85045 300 cm-1, and an unambiguous assignment of angular momenta was given to most of the energy levels in accordance with the electric dipole selection rules.
