Diffraction theory for very-high-energy scattering

High-energy Scattering and Diffraction: Theory Summary A

New developments in the theory and phenomenology of high-energy scattering and diffraction that were presented and discussed at DIS2000 are reviewed.

Very low-energy electron scattering from benzene: experiment and theory

Low-energy collision studies have shown that the scattering cross section for electrons by benzene rises sharply at electron impact energies below∼ 200 meV. This was attributed in earlier work to electron attachment and formation of benzene anions with lifetimes τ 1μs. A detailed study of electron attachment to benzene is reported here that makes use of Rydberg atom techniques. The data provide...

Inelastic Hadron Diffraction in High Energy Elastic Scattering of Nuclei

Inelastic hadron diffraction refers to quasi-elastic transitions in which the colliding particles conserve their dominant quantum numbers. High energy of collision facilitates to satisfy the condition of coherence thus assuring that interaction does not change the character of the particles. High energy elastic scattering of hadrons is thus generally built of: i) elastic diffraction which resul...

High Energy Synchrotron Diffraction

High energy synchrotron diffraction is introduced as a new method for residual stress analysis in the bulk of materials. It is shown that energy dispersive measurements are sufficiently precise so that strains as small 10-4 can be determined reliably. Due to the high intensity and the high parallelism of the high energy synchrotron radiation the sample gauge volume can be reduced to approximate...
