Combining elastic and inelastic processes with transfer reactions, this two-part volume explores how these events affect heavy ion collisions. Special attention is given to processes involving the transfer of two nucleons, which are specific for probing pairing correlations in nuclei.

Fragment production in heavy-ion reactions
Physical Review C, 1992We calculate the yield of projectile-like fragments in intermediate and high energy heavy-ion reactions using an abrasion-ablation model. We use the distribution of holes left by the abraded nucleons to estimate the primary-fragment excitation energies and calculate the statistical emission using this energy distribution.

MULTIMODAL FISSION IN HEAVY IONS INDUCED REACTIONS
Seminar on Fission, 2004Mass, energy and folding angle distributions of the fission fragments as well as multiplicities of neutron and gamma-quanta emissions accompanying the fission process were measured for fission of 226Th, 227Pa and 234Pu compound nuclei produced in reactions with 18O and 26Mg projectiles over a wide energy range.

Polarization in heavy ion reactions
AIP Conference Proceedings, 1981For various heavy ion reactions we discuss from kinematical constraints and classical models the average behaviour of the nuclear polarization of the excited residual target and projectile like fragments and compare with measurements where these polarizations are derived from the circular polarization of deexcitation gamma rays emitted into the ...

Strangeness and heavy ion reactions
Nuclear Physics A, 1988Abstract We investigate possible consequences of strangeness formation in heavy ion reactions at different excitation energies. First of all we study ground state properties of multi-Λ hypernuclei. They seem to have strongly enhanced interaction radii and could be observed and produced in secondary non charge changing reactions of high energy heavy ...

Bremsstrahlung in heavy-ion reactions
Zeitschrift f�r Physik A Atoms and Nuclei, 1975We investigate bremsstrahlung processes induced by heavy ions: nuclear dipole and quadrupole radiation, radiation from bound target electrons into the continuum and secondary electron bremsstrahlung (SEB), which contribute to the background of the X-ray spectra. A comparison with experiment is presented.

Reports on Progress in Physics, 1977
This review is a non-technical outline of our understanding of the mechanisms of heavy-ion transfer reactions, of what has been learned about the nucleus from the use of these reactions, and of the problems presently being investigated. The subject matter is chiefly restricted to reactions in which transitions to individual levels can be resolved and ...

Polarizations in Heavy-Ion Reactions
Physical Review Letters, 1978The polarizations of products of quasielastic heavy-ion reactions are discussed in the framework of the distorted-wave Born approximation and are shown to depend upon the bombarding energy, $Q$ value, and specific reaction products. A sign change of these polarizations (which is unrelated to negative-angle scattering) is expected as a function of ...

Polarization in heavy-ion reactions
Hyperfine Interactions, 1985A series of experiments is described in which beta-ray asymmetry has been used to determine polarization of heavy-ion reaction products12B and the present status of the studies of polarization phenomena in heavy-ion reactions is reviewed. A large amount of angular momentum sustained by the two colliding nuclei gives rise to polarization phenomena of ...

Spallation and heavy ion reactions
Physica, 1956Synopsis The reactions discussed are those in which enough energy is available to liberate several heavy particles. No rigid separation between spallation and heavy ion reactions is possible but it is convenient to make some distinction. The term spallation will be limited to those reactions emitting several particles in which the average kinetic ...
