- Abstract
The high-resolution spectra of 110 transitions in Nd II over the range 418–465 nm were observed using the collinear fast-ion-beam/laser method (FIBLAS). The lower states of these transitions include the ground state and 10 metastable even-parity states with energies up to 5986 cm–1. The 64 odd-parity upper states have energies up to 29 434 cm–1. For each transition isotope shifts were measured for all the stable isotopes (mass numbers 142, 143, 144, 145, 146, 148, and 150), as well as hyperfine parameters for the two odd-mass-number isotopes. These quantities are important in modeling profiles of absorption lines in stellar atmospheres to obtain abundances, and in the classification of atomic energy levels.
