摘要：

Coherent forward scattering spectroscopy in combination with continuum sources allows simultaneous or sequential multielement determination. Since the brightness of the Xe light source does not depend on the strength of the measured atomic lines, the dynamic range can be strongly expanded by measuring on resonance lines of extremely different strengths. Major constituents can be determined on very weak lines, which are too weak for atomic absorption methods using common line sources. Analytical curves for strong and weak alkali lines are presented as well as curves for the group II elements Ca, Mg and Cd, using the strong singlet and the weak singlet-triplet intercombination lines. © 1990.
