Abstract
ECENTLY a number of authors(George, Redding and Trent 1953, Leonticand Wolfendale 1953) have published results of measurements on the scattering R of {L-mesons using the cosmic radiation. The present experimental data are not conclusive, but there seems to be some indication that the cross sections obtained are inconsistent with coulomb scattering from a nucleus with an extended charge distribution. We give here results of calculations made in an attempt to explain the anomalously large scattering cross section. The contribution to the scattering of p-mesons, arising from the anomalous magnetic moment (A.M.M.) of the nucleon and from a possible A.M.M. of the pmeson, has been worked out. The lowest-order process for this scattering in weak-coupling theory is shown.
