An optical-potential model originally developed for low-energy (T[sub [pi]] [le] MeV) pion-nucleus scattering in momentum space was extended to treat both kaon-nucleus and high-energy pion-nucleus elastic scattering ( MeV [le] T[sub [pi]] [le] 1 GeV).

In nuclear physics, the Optical Model means, we are treating the scattering problem is like optical wave problem. due to the incident beam can be treated as a wave-function. and this wave will be scattered by the target.. when the beam is far away from the target, the wave function of the incident beam should satisfy the Schrödinger equation in free space. These microscopic optical potentials are compared with that of Dirac phenomenology (DP) for the polarized proton-{sup 40}Ca elastic scattering at 35 MeV and MeV. These potentials have different shapes for MeV below 4 fm.

An optical model calculation of proton and K meson scattering from ³He Public Deposited. Analytics × Add Author: Manuel José Paéz-Mejía. A study is made of proton and K meson scattering from the ('3)He using a microscopic optical potential derived from multiple scattering theory.

The two-body scattering lengths, which describe the interaction between K −-mesons and free nucleons are used to calculate an optical model potential representing the interaction between K −-mesons and by: 3.

We will analyse the proton scattering from light nuclei in the intermediate energy range. By intermediate energy we mean from 50 MeV up to MeV.

The analyses will concentrate mainly on 12C target. Since this is a. Therefore, optical model analysis was employed to calculate the elastic scattering cross section for p +4 0 Ca interaction at energies from 9 to 22 MeV as well as the polarization at energies from 10 to MeV.

Its use can be extended to inelastic scattering and to perform calculations for a wide variety of. Optical Model Analysis The optical model potential between the incident proton and the target nucleus was assumed to have the usual form V(r) = Vc(r)+(U+iWv)f(r)+iWDg(r)-Us r dr 1.

8 Probing the Proton: Electron - Proton Scattering Scattering of electrons and protons is an electromagnetic interaction.

Electron beams have been used to probe the structure of the proton (and neutron) since the s, with the most recent results coming from the high energy HERA electron-proton collider at DESY in Hamburg.

Mott Scattering Scattering of a relativistic electron by a pointlike spin 1/2 proton Similar to electron muon scattering from last Lecture Usually described in the Lab frame, where the proton is at rest: θ is the lab scattering angle of the electron pe is the incident electron beam momentum q2 is the four-momentum transfer of the virtual photon.

A model for highly inelastic electron-nucleon scattering at high energies is studied and compared with existing data. This model envisages the proton to be composed of pointlike constituents. The calculation of the complete set of P(2) splitting functions by Moch, Vermaseren and Vogt (hep-ph/,) completes the calculational tools for a consistent NNLO pQCD treatment of Tevatron & LHC hard-scattering cross sections.
