Abstract
The spectrum of transitions to high-lying odd states of the neodymium atom in the UV range from 317 to 323 nm is studied by resonance laser excitation and ionization. Fifty-five of the 72 transitions detected are observed for the first time. For the brightest lines (18), the lower levels of transitions are identified, the energies of the upper levels are determined (31023.813–33437.403 cm–1), and the isotope shifts between 142Nd and 144Nd are measured. The shifts for all stable even neodymium isotopes are measured for five transitions (142–150).
