Elastic scattering of 2.0 GeV/c negative pions off protons

Abstract

An experimental study of the elastic scattering of negative pions off protons at 2.0 GeV/c is presented. The differential cross section is fitted to a polynomial in cos θc.m. and the forward angular region as a diffraction peak. The results are compared with those from other bubble chamber experiments at neighbouring energies and discussed in terms of optical model and possible exchange trajectories. © 1969.
