New and Alternative Line Identifications in Solar Chromospheric and Photospheric Spectra

Observed chromospheric emission-line wavelengths in the Pierce (1968) solar line list are compared with wavelengths in the laboratory list of Striganov & Sventitskii (1968) and more recent laboratory lists. A large number of close wavelength agreements are found for lines of higher abundance lower Z elements, providing new assignments for unidentified solar lines and alternative, more likely assignments for some solar lines which have been ascribed to low-abundance heavy elements and rare earth elements. Wavelength coincidences are found,also for lines of the rare gas elements, raising questions of verification which are important for the general problem of abundances. A limited examination of the photospheric spectrum shows that similar new assignments can be made in that spectrum.
