Graphical Method for Obtaining Phase Shifts from the Experimental Data on Meson-Nucleon Scattering

Abstract

A graphical method is used for obtaining scattering phase shifts from the experimental data on meson-nucleon scattering. The method is based on the observation that the imaginary part of the amplitude for coherent forward scattering is proportional to the total cross section for the meson scattering. The results are in agreement with a complete numerical analysis of the problem made by Fermi with the help of the high-speed electronic computer at Los Alamos.
