Polarization in Heavy-Ion Scattering
1976Elastic-scattering polarization P and inelastic-scattering spin-flip probabilities P1 are calculated in a model1) for the spin-orbit interaction. The model considers a single valence orbit bound to a spin-zero core. Both 13C and 15N can be so considered, since their 1p1/2 spectroscopic factors S are large2).

Reflection in heavy ion elastic scattering
Nuclear Physics A, 1990Abstract The reflective model for heavy ion elastic scattering is discussed in its classical, semi-classical and quantum mechanics formulation. The model assumes that the reflection is the dominant scattering mechanism for the particles which hit the nuclear surface.

Nuclear rainbows and heavy-ion scattering
Nuclear Physics A, 1984Abstract We discuss refractive effects on scattering in the presence of strong absorption, and conclude that a residuum of a true nuclear rainbow has been seen only for light ions. Such a rainbow seems to be unlikely for heavy ions because of their stronger absorption.

Effects of triple scattering in heavy-ion reactions
Physical Review C, 1995This 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, 1980By 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, 1994Abstract 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.

Polarization potentials in heavy-ion scattering
Physics Reports, 1984Abstract A polarization potential is defined in terms of the Feshbach projection operator formalism to represent the effect upon the elastic channel of the coupling to non-elastic channels in heavy-ion scattering. The polarization potential represents coupling to specific surface degrees of freedom of the particular reaction considered and it is ...

Deep inelastic scattering of heavy ions
Progress in Particle and Nuclear Physics, 1980Abstract 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, 1997Angular 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.
