Popis:	Based on Lund recordings, this communication reports 380 classified lines of the doubly ionized zirconium atoms. These classifications led us to confirm the energy levels belonging to the configurations 4s24p64d2, 4d5s, 4d6s, 4d5p, 4d5d, 4d4f, 5s6s, 5s5p, 5s5d, 5s4f and 5p2. All the levels of 4d6p and 5s2 have been revised, along with 1H5 of 4d4f. The configurations 4d6d, 4d5f, 5s6p and 5s5f have been newly worked out to almost completeness. The total number of the known energy levels of Zr III is now 137 including 41 levels freshly added. We derive from nd series the ionization energy of Zr III to be 186 400 ± 500 cm-1 (23.11 ± 0.06 eV).
