Differential Cross Sections for Compton Scattering Off the Proton at 185 MEV
A complete angular distribution of Compton scattering off the proton was measured at average laboratory bremsstrahlung energy of 185 MeV. The experiment was per-formed at the Saskatchewan Accelerator Laboratory using the new high duty factor elec-tron beam. The scattered photons were observed with …

Diffractive jet production in deep inelastic e + p collisions at HERA
A measurement is presented of dijet and 3-jet cross sections in low-t diffractive deep-inelastic scattering interactions of the type ep->eXY, where the system X is separated by a large rapidity gap from a low-mass baryonic system Y. Data taken with the H1 detector at HERA, corresponding to an …

Computer Calculations of Cross Sections for Electron Impact Ionization of Helium
Triple differential cross sections for electron-impact ionization of helium are calculated in the distorted wave approximation. The distorted wave formalism is discussed for the z-axis parallel to the momentum transfer direction. Problems associated with programming this formalism are outlined. The …

Production of omega and phi mesons by 193 GeV/c pions and 250 GeV/c protons on a beryllium target
Qmegas and phis were observed in di-muon events. Differential cross sections with respect to perpendicular momentum and Feynman-X for both meson types and both beam types are compared. When a simple parton fusion model is used to describe the Feymnan-X distributions the omega appears to be produced …
