Total Cross Section for Positive Pions in Hydrogen

Authors: Leonard, Stanley L.; Stork, Donald H.;

Total Cross Section for Positive Pions in Hydrogen

Abstract

The total cross section for positive pions in hydrogen has been measured at pion kinetic energies of 33, 44, 56, and 70 Mev. The attenuation of pions of these energies in liquid hydrogen was studied by scintillation-counter techniques. The geometry was such that pions scattered at angles greater than \ifmmode\pm\else\textpm\fi{}35\ifmmode^\circ\else\textdegree\fi{} were counted as having been removed from the beam. Therefore, the term "total cross section" is taken to mean the cross section for all interactions except those in which the pion is scattered into an angle of less than \ifmmode\pm\else\textpm\fi{}35\ifmmode^\circ\else\textdegree\fi{} from the pion-beam direction. The results are: The energy dependence of the cross section seems to agree with the predictions of lowest-order perturbation theory for pseudoscalar mesons with gradient coupling to the nucleon.
