Effects of triple scattering in heavy-ion reactions

Physical Review C, 1995
This work studies the effect of a high-density correction to the Boltzmann-Uehling-Uhlenbeck (BUU) dynamics, i.e., the inclusion of triple scattering in heavy-ion reactions at intermediate incident energies. By using both schematic model calculations and the modified BUU simulations with triple scatterings incorporated, it has been suggested that the ...

Heavy-ion scattering from strongly absorbing optical potentials

Il Nuovo Cimento A, 1980
By using the Watson transformation the heavy-ion optical-potential scattering amplitude is decomposed in the sum of a Regge-pole and a saddle point contribution. Outside a critical angular interval the saddle point contribution can easily be evaluated by using nonuniform asymptotic techniques and it is possible to assign a simple physical ...

Scattering of heavy ions in crystals

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1994
Abstract A physical model is constructed to describe the recapture of low energy heavy ions into axial channels in kinetic approach (rechanneling effect). This model includes the main essential physical processes.

Deep inelastic scattering of heavy ions

Progress in Particle and Nuclear Physics, 1980
Abstract These lecture notes show how path integral methods can be used in the theory of heavy ion reactions. The effects of internal degrees of freedom on the relative motion are contained in an influence functional which is calculated for several simple models of the internal structure.

Atomic Effects on Heavy-Ion Scattering

Physical Review C, 1997
Angular distributions of a Pb-208 beam on Pb-208 thin targets at very small angles were measured. The shape of the experimental distribution is not Gaussian, indicating a plural scattering regime rather than multiple scattering. The distribution was well reproduced by a Monte Carlo simulation of the straggling process.

Parity dependence in heavy-ion scattering

Nuclear Physics A, 1986
Abstract The parity dependence of collisions between p- and sd-shell nuclei is studied microscopically in the two-centre harmonic oscillator model. A simple rule giving the sign of the odd-even part of the potential is established. Besides the well-known dependence on the nucleon-number difference, a marked variation of the parity effect with the ...

Diffraction theory of heavy-ion scattering

Journal of Physics G: Nuclear Physics, 1976
Detailed analysis of phase-amplitude curves is found to provide much insight into the elastic scattering of heavy ions at intermediate and high energies, where numerical calculations become lengthy. The nuclear interaction is first treated by the strong absorption model, and a semiclassical analysis providing a link with Fresnel diffraction is found to

Deformation effects in heavy-ion scattering

Nuclear Physics A, 1974
Abstract Many experiments on the scattering of heavy ions confirm that the elastic cross sections display characteristics of Fresnel diffraction. Recent experiments on the scattering of very heavy ions, however, show marked deviations from the expected Fresnel shapes and an analysis of these experiments using the “quarter-point-recipe” of the Fresnel
