| Abstract: | Laser light intensity correlation spectroscopy is used to measure bacterial motility. The angular dependence of the scattering spectra from motile E. Coli K12 bacteria is in agreement with theoretical predictions. By taking appropriate integrations of the spectra, the swimming speed distribution of the bacteria is determined. |
