Abstract
The Ramsauer technique has been used to measure absolute total -Ar scattering cross sections from 0.1 to 21.6 eV with an estimated probable error of ±3%. A phase-shift analysis of the data (for the partial waves) has been made using "modified effective range" theory which yields a scattering length of -1.65 and a minimum total cross section of 0.125 at 0.285 eV.
