Abstract:

Cross sections for the production of negative protons in various processes was calculated assuming the pseudoscalar meson theory. Numerical results are summarized in Table II, §5. In the lack of satisfactory theory for the high energy processes considered here, we have employed the Weizsäcker-Williams method. Taking account of the reactions and the non-linearities of the meson field phenomenologically to some extent, we have treated the case of modified meson spectrum as suggested by Heisenberg. Obtained cross sections for the production of negative protons by the nucleon-nucleon collisions are smaller by the factor of about 10-4 in the case of modified meson spectrum than those in the case of neglecting the reactions and non-linearities of meson field completely. Also the cross section for the production of negative protons by proton-proton collisions near threshold is calculated by the method of Feynman's relativistic perturbation.
