Proton-Nucleus Scattering at Very High Energy

Inelastic Profon - Proton Scattering at Very High Energy

On High - Energy Inelastic Electron - Proton Scattering

High-energy pion-nucleus elastic scattering.

We investigate theoretical approaches to pion–nucleus elastic scattering at high energies (300 ≤ Tπ ≤ 1 GeV). A “model–exact” calculation of the lowest–order microscopic optical model, carried out in momentum space and including the full Fermi averaging integration, a realistic off–shell pion–nucleon scattering amplitude and fully covariant kinematics, is used to calibrate a much simpler theory...

Proton–Nucleus Cross Section at High Energies

Cross sections for proton inelastic collision with different nuclei are described within the Glauber and multiple scattering approximations. A significant difference between approximate “Glauber” formula and exact calculations with a geometrical scaling assumption for very high-energy cross section is shown. Experimental values of proton–proton cross sections obtained using extensive air shower...

0 Polarized Proton Nucleus Scattering

We show that, to a very good approximation, the ratio of the spin-flip to the non-flip parts of the elastic proton-nucleus amplitude is the same as for proton-nucleon scattering at very high energy. The result is used to do a realistic calculation of the analyzing power A N for pC scattering in the Coulomb-nuclear interference (CNI) region of momentum transfer.
