1950 A. S. Bishop Photoproduction of Mesons from Hydrogen (Univ. of Calif. Radiation Lab., UCRL-874) 40 By definition, σ(Eph), the excitation function at 90° for photo-meson production from protons, constitutes the probability that a photon of energy Eph, interacting with a proton, will produce a meson at 90° in the laboratory system.
1969 Physical Rev. 177 2500 Predictions are made for high-energy charged photomeson production cross sections in which the bombarding photon is polarized.
2003 Astrophysical Jrnl. 595 346 Young, rapidly rotating magnetars whose spin and magnetic moment point in opposite directions emit high-energy neutrinos from their polar caps through photomeson interactions.
