doi:10.7523/j.issn.2095-6134.2017.01.003

Abstract

Abstract:

In this work, the fine structure of Sm I was calculated with the experimental fitting method, which is based on the non-relativistic atomic energy expressions with the relativistic correction. For the ground configuration[Xe]4f⁶6s², the results of different fitting procedures are compared with the experimental data, and the effects of various parameters on the energy levels are analyzed. For odd parity configurations 4f⁶6s6p+4f⁵5d6s², the 134 accurate known energy levels are obtained by using 22 fitted experimental energy levels. For even parity configurations 4f⁶6s²+4f⁶5d6s+4f⁶6s7s, the 65 accurate known energy levels are obtained by using 17 fitted experimental data. Five high-lying levels are assigned to even-parity 4f⁶(⁷F)6s7s ⁵F_J(J=1-5).

Key words: Sm I, fine structure energy levels, fitting method
