Abstract

The spectrum of doubly ionized neon (Ne III), emitted from hollow-cathode and theta-pinch discharges, has been photographically recorded in the 430 - 12 000-angstrom wavelength range. The number of classified lines has been increased from about 100 to about 750, and the number of experimentally established energy levels from 60 to 230. The level scheme comprises levels in the 2s(2)2p4, 2s2p5, 2p6, 2s(2)2p(3)3s-8s, 3p-5p, 3d-5d, 4f-8f, and 5g-7g configurations. The experimentally observed level distribution are compared with the results of Hartree-Fock calculations and least-squares fits.
