Absolute total scattering cross sections have been measured for electron scattering from krypton in the energy range 0.175-20 eV. The measurements have been performed with a linear time of flight electron transmission spectrometer. Comparisons are made with the results of a number of other experiments and theoretical calculations and the agreement is generally good. However, at low energies, particularly in the region of the Ramsauer minimum, the present results and the recent measurements of Jost et. al. differ by more than 30%. A momentum transfer cross section is derived from the data by the use of the modified effective-range theory to enable direct comparison with swarm-derived cross sections.
