Book excerpt: 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. This novel treatment provides, together with the description of surface vibration and rotations, a unified picture of heavy ion reactions in terms of the elementary modes of nuclear excitation. Heavy Ion Reactions is essential reading for beginning graduate students as well as experienced researchers.

Available in PDF, EPUB and Kindle. Book excerpt: With the advent of heavy-ion reactions, nuclear physics has acquired a new frontier. The new heavy-ion sources operating at electrostatic accelerators and the high-energy experiments performed at Berkeley, Dubna, Manchester and Orsay, have opened up the field, and have shown us impressive new prospects. The new accelerators now under construction at Berlin, Daresbury and Darmstadt, as well as those under consideration (GANIL, Oak Ridge, etc. ) are expected to add significantly to our knowledge and understanding of nuclear properties. This applies not only to such exotic topics as the existence and lifetimes of superheavy elements, or the possibil ity of shock waves in nuclei, but also to such more mundane issues as high-spin states, new regions of deformed nuclei and friction forces. The field promises not only to produce a rich variety of interesting phenomena, but also to have wide-spread theoretical implications. Heavy-ion reactions are characterized by the large masses of the fragments, as well as the high total energy and the large total angular momentum typically involved in the collision. A purely quantum-mechanical description of such a collision process may be too complicated to be either possible or inter esting. We expect and, in some cases,know that the classical limit, the limit of geometrical optics, a quantum-statistical or a hydrodynamical description correctly account for typical features.

Available in PDF, EPUB and Kindle. Book excerpt: If two nuclei could be placed next to each other at a distance typical of grazing collisions, the single-particle states in each would adjust themselves to the presence of the other nucleus. They would develop an appreciable probability of being in the other nucleus, and the more weakly bound the state, the more strongly it would be polarized by the other nucleus. The solution to this situation has been realized in the two-center shell model. Whether such an adjustment can occur during a reaction depends on the ratio of the transit time to the nuclear periods of the more weakly bound nucleons. In typical low-energy experiments this ratio appears to allow for such a polarization. Clearly if it occurs, the form factor for a transfer reaction will be modified from those currently employed, which use the asymptotic single-particle states of the non-interacting separated nuclei. From the foregoing discussion it is expected that (1) for stripping reactions to a sequence of excited states in the target nucleus, the polarization effects will increase with increasing excitation (i.e., decreasing binding), (2) since transfer can take place for larger impact parameters if polarization occurs, the effect on the angular distribution will be a shift to smaller angles compared to normal DWBA, (3) the polarization effect will ultimately vanish at sufficiently high bombarding energy. Calculations so far show that the single particle states of the heavier of the reaction partners suffer the greater polarization. 2 figures.
Download or read book Theoretical Approaches of Heavy Ion Reaction Mechanisms written by M. Martinot and published by Elsevier. This book was released on 2016-06-03 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical Approaches of Heavy Ion Reaction Mechanisms provides information pertinent to heavy ion reactions and nuclear fission at low energies. This book discusses the features of the time-dependent solution of the Kramer–Chandrasekhar equation. Organized into 27 chapters, this book begins with an overview of the deexcitation process of a highly excited nucleus by means of its decay into two fragments. This text then presents a microscopic description to extract the characteristics features of the collective dynamics of the fission process at low energy. Other chapters consider nuclear fission as a transport process over the fission barrier. This book discusses as well the microscopic foundations of the phenomenological collective models. The final chapter deals with the composition of the baryons and mesons in terms of gluons and quarks. This book is a valuable resource for nuclear and high energy physicists. Experimentalists, theoreticians, and research workers will also find this book useful.

Available in PDF, EPUB and Kindle. Book excerpt: For 75 years the stopping of energetic ions in matter has been a subject of great theoretical and experimental interest. The theoretical treatment of the stopping of ions in matter is largely due to the work of Bohr, 1-3 Bethe,4-6 Bloch,7. s and Lindhard,9-12 and it has been reviewed by Bohr,3 Fano,13 17 20 Jackson,14 Sigmund,15 Ahlen,16 and Ziegler et al. - Soon after the discovery of energetic particle emission from radioactive materials, there was interest in how these corpuscles were slowed down in traversing matter. In 1900, Marie Curie stated 21 the hypothesis that Hies rayons alpha sont des projectiles materiels susceptibles de perdre de leur vitesse en travers ant la matiere. " Early attempts to evaluate this were incon clusive for there was not yet an accurate proposed model of the atom. Enough experimental evidence was collected in the next decade to make stopping power theory one of the central concerns of those attempting to develop an atomic model. J. J. Thomson, director of the prestigious Cavendish Laboratory, and Niels Bohr, a fresh postdoctoral scientist at Rutherford's Manchester Laboratory, both published almost simultaneously22. 23 an analysis of the stopping of charged particles by matter, and each contained many of their divergent ideas on the model of an atom. Thomson ignored in his paper the Rutherford alpha-particle scattering 24 experiment of a year before. But the nuclear atom with a heavy positively 25 charged core was the basis of Bohr's ideas.
Download or read book Transition from Quasi elastic to Deep inelastic Reactions written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy ion induced transfer reactions are usually considered to fall into two categories. Quasi-elastic processes, on one hand, are characterized by small energy transfers, with one-nucleon transfer reactions being a typical example. These processes are dominant for grazing collisions, and are generally described within simple one-step DWBA calculations. Deep inelastic reactions, on the other hand, occur for more central collisions where the interaction time is longer and subsequently more energy and particles can be exchanged. Quasi-elastic collisions dominate transfer reactions induced by light heavy ions (e.g., 16O) at energies not too high above the barrier, while deep inelastic collisions are observed mainly in reactions induced by heavier projectiles (Kr, Xe). In this contribution, we discuss the transition between these two processes for the system 48Ti + 2°8Pb. 48Ti is located between light (16O) and heavy (Kr) projectiles and should be well suited for a study of the interrelation between quasi- and deep-inelastic reactions. The experiments were performed with a 300 MeV 48Ti beam obtained from the Argonne National Laboratory superconducting linac. The outgoing particles were momentum analyzed in a split pole magnetic spectrograph and detected in the focal plane by a position sensitive ionization chamber. The specific energy loss, the magnetic rigidity and the total energy of the outgoing particles were measured enabling mass and Z-identification. The energy resolution was about 3 MeV, determined by the thickness of the 2°8Pb target, and thus excluded study of transfer reactions to discrete final states. Angular distributions were measured in the range theta/sub lab/ = 20° to 80° in steps of 5°. 8 refs.
