摘要

The energy levels of singly ionized neodymium (Nd II) are interpreted following the Racah-Slater parametric method, by using the Cowan computer codes. Radial parameters obtained in a least-squares fit are compared with Hartree-Fock (HFR) ab initio integrals. In the odd parity, 596 levels of the mixed configurations 4f~35d6s, 4f~35d~2, 4f ~36s~2, 4f~46p and 4f~5 are used to determine 39 free parameters, 51 other parameters being constrained. The mean error is 53 cm~(-1). The configuration sharing of the levels is supported by the experimental isotope shifts ~(144)Nd-~(150)Nd.
