An analysis is carried out on the relative importance of the various atomic processes in photoionized plasmas as a function of the electron temperature and irradiation conditions. In particular, we investigate the influence of K-shell photoionization of Li-like ions on the Hespectrum and of Be-...

wavelength from radiation falling upon it if the incident radiation contains light of this wavelength. For example, theD-lines of the emission spectrum ofsodiumare found as absorption lines in the same position (i.e. of the same wavelengths) when “white” light is passed throughsodium vapour....
The accuracy of wavelength measurements is limited by that of the spectrograph or interferometer used for dispersing the LIF spectrum. Higher spectral resolution can be achieved by stimulated emission pumping, where a second tuneable laser L2 is used to induce stimulated emission from the excited level...

The emission spectrum of ZrCl has been observed in the 1800-12 000 cm(-1) region using a Fourier transform spectrometer. The molecules were excited in a microwave discharge of a mixture of helium and a trace of ZrCl(4) vapor. In addition to the C(4)Delta-X(4)Phi transition reported...
