Abstract
The wavelengths of the 2l-nl' (n = 4-15) spectral lines of Ne-Like Ni XIX a nd Ge XXIII were measured in laser-produced plasmas. The accuracy of these measurements (0.5-2.5 m Angstrom) is a large improvement over previous resu lts, and a number of transitions (mainly from levels with n = 8-15) were ob served for the first time. The 2P(3/2)-nd(5/2) and 2p(1/2)-nd(3/2) Rydberg series were used to determine the first two ionization limits of the ground states of Ni XIX and Ge XXIII. Effects of configuration interaction were o bserved in the intensities of some spectral lines.
