A small-angle intensity fluctuation spectrometer has been constructed and used to measure the width Gamma of the Rayleigh component of 514.5-nm light scattered from liquid helium. The techniques utilized to maximize the weak scattered signal are described. Measurements of Gamma at small angles (65theta < 104="" mrad)="" as="" a="" function="" of="" temperature="">T<4.3 k)="" and="" pressure="">P<1.42 mpa)="" agree="" with="" predictions="" based="" on="" hydrodynamic="">
