Zeeman Laser Scattering (ZLS): a new light scattering technique
A new light scattering technique, called Zeeman Laser Scattering (ZLS), which uses a two-frequency Zeeman effect laser, is described. The Zeeman effect laser produces two coherent, colinear laser beams having orthogonal polarizations. The laser output is passed unfocused through a scattering cell containing the sample of interest, and the light scattered at each scattering angle is detected with a photomultiplier tube mounted on an arm that rotates under computer control about the scattering cell. The phase and amplitude of the beats produced by the interference of the two colinear laser beams are measured. Three different scattering mechanisms to which ZLS is sensitive are described, and the quantitative theory of ZLS is derived from the scattering amplitude matrix formalism. Samples of ZLS data are given. (LEW)
