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...
متن کاملMicroscopic Optical Potentials for Elastic Nucleon-Nucleus Scattering
The theoretical approach to the elastic scattering of a nucleon from a nucleus, pioneered by Watson [1], made familiar by Kerman, McManus, and Thaler (KMT) [2] and further developed as the spectator expansion [3, 4, 5, 6] is now being applied with striking success. In a similar vein, a slightly di erent approach to the multiple scattering expansion within the KMT framework is being pursued by t...
متن کاملSlope analysis for elastic nucleon-nucleon scattering
The diffraction slope parameter is investigated for elastic proton-proton and proton-antiproton scattering based on the all available experimental data at low and intermediate momentum transfer values. Energy dependence of the elastic diffraction slopes is approximated by various analytic functions. The expanded ”standard” logarithmic approximations with minimum number of free parameters allow ...
متن کاملMultiple scattering theory of proton elastic scattering at intermediate energies.
We derive and calculate the multiple scattering expansion of the Kerman-McManus-Thaler optical potential to second order in the free nucleon-nucleon transition amplitude and clarify the physical content of the interaction. Calculations are presented for the elastic scattering of protons from ' 0 at 135, 200, and 300 MeV incident energies, paying particular attention to the nonlocalities inheren...
متن کاملEquivalent local potentials to multiple scattering calculations of nucleon-nucleus scattering.
Local phase equivalent interactions to the nonlocal Kerman, McManus, and Thaler multiple scattering nucleon —nucleus optical potentials are determined. Both firstand second-order contributions in the free nucleon-nucleon transition amplitude are included. The second order terms modify the derived potentials in a nontrivial way and reduce the strengths of the real and imaginary central potential...
