Elastic and inelastic scattering of heavy ions
Nuclear Physics, 1966Abstract The elastic and inelastic scattering of heavy ions from nuclei are considered in terms of a generalized optical model. Amplitudes for the single excitation of target or projectile are evaluated in distorted waves approximation, while amplitudes for more complicated excitations, such as double excitation or mutual excitation of both nuclei ...

Critical scattering in heavy ion reactions
Zeitschrift f�r Physik A Hadrons and Nuclei, 1992Heavy ion reactions at intermediate energies are mostly described by the VUU equations. Using methods of quantum statistics we derive a useful relation between the width of s.p. states and the density — density correlation function. Near the point of instability from this relation there follows the increase of the collision integral and enhanced ...

Parity dependence in heavy-ion scattering [PDF]
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 ...

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.

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.

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.

Elastic and inelastic heavy ion scattering
Physics Reports, 1978Abstract We present a detailed study of a representative set of elastic and inelastic heavy ion scattering data by means of a closed formalism that depends entirely on the properties of the elastic scattering matrix. This formalism, which gives an explicit representation of the essential features of optical model and distorted wave amplitudes ...

Intermediate structure in heavy ion scattering
Zeitschrift f�r Physik A Atoms and Nuclei, 1983It is shown that the nucleon-state structure in the cold, strongly deformed nucleus formed when two nuclei collide may be responsible for anomalies such as those observed in recent experiments.

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.
