A low angle quasi-elastic light scattering investigation of Chlamydomonas reinhardtii

This paper outlines the results of the first homodyning low angle scattering experiment known to have been reported for motile particles. Low angle scattering QELS studies were carried out on a wild strain of Chlamydomonas reinhardtii at scattering angles of 3.3 degrees, 2.6 degrees and 1.7 degrees. The resultant experimental autocorrelation functions and scaling curves were compared with a theoretical model that had been successful previously at scattering angles greater than 15 degrees.
