| Popis: | New measurements of the optical spectrum of trivalent neodymium in a hexagonal lanthanum chloride host have been made at 4 and 77 K at wavelengths down to 2500 A (40 000 cm−1). Crystal quantum number assignments for new energy levels were derived from these results and for most of the earlier levels not already classified. A least‐squares fit with a mean error of 8.1 cm−1 was carried out for 101 levels, using 20 adjustable parameters in a Hamiltonian containing operators for two‐ and three‐particle electrostatic interactions; spin–orbit, spin–other‐orbit and spin–spin magnetic interactions; two‐particle pseudomagnetic configuration‐mixing interactions; and single‐particle crystal‐field interactions. |
