✦ Synopsis

The wavelengths and intensities of the stronger transitions in the spectrum of Ni XlX are reduced from measurements of the X-ray spectra of three coronal active regions. The new measured wavelengths are consistent with prediction by isoelectronic extrapolation from the wavelengths of well established transitions but are about 0.01 A longer than previously accepted laboratory measurements. This difference appears to be crucial to the correct assignment of features in the coronal spectrum to NixLx. The relative intensifies of our new assignments to Nixlx are in broad agreement with the Loulergue-Nussbaumer calculations.
