Download or read book Heavy Ion Interactions Around the Coulomb Barrier written by Cosimo Signorini and published by Springer. This book was released on 1988-12-07 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear reactions at energies near and below the Coulomb barrier have found much interest since unexpectedly large cross sections of fusion for heavy ions were discovered around 1980. This book covers the more important experimental and theoretical aspects such as sub-barrier fusion, sub- and near-barrier transfer, couplings of various reaction channels, neck-formation, the threshold anomaly, spin distributions and fusion of polarized ions. The symposium also included a session devoted to mass spectrometry for fast reaction products.

This book was released on 1993-11-01 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses primarily the characteristics of reactions induced by unstable nuclei and aims to guide future directions in this area of research. In addition, the present status of research in related fields is reviewed. The topics discussed can be broadly classified into: fusion and transfer reactions with stable nuclei, fission and molecular resonance, structure of unstable nuclei, reactions with unstable nuclei, synthesis of superheavy elements and heavy-ion fusion with neutron-rich beams.
Download or read book The Threshold Anomaly for Heavy ion Scattering written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The real parts of optical potentials deduced from heavy-ion scattering measurements become rapidly more attractive as the bombarding energy is reduced close to the top of the Coulomb barrier. This behavior is explained as a coupled-channels effect, and is related to the corresponding reduction in the absorptive potential through a dispersion relation which expresses the consequences of causality. Another manifestation of this ''anomaly'' is the striking enhancement observed for the near- and sub-barrier fusion of two heavy ions. The barrier penetration model of fusion is examined critically in this context. It is also stressed that similar anomalies could appear in the energy dependence of nonelastic scattering. 21 refs., 4 figs.

This book was released on 1993-07-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This symposium on Reflections and Directions in Low Energy Heavy-Ion Physics celebrates twenty years of the University Isotope Separator at Oak Ridge (UNISOR) and ten years of the Joint Institute for Heavy Ion Research (JIHIR). It reflects on the accomplishments in low energy heavy-ion science and emphasizes the new directions and opportunities to be explored with low energy heavy-ion facilities. It includes a special section devoted to structure theory and another emphasizing new research to result from facilities exhibiting radioactive ion beam capabilities, new generation recoil mass spectrometers and sophisticated gamma-ray detector arrays. With the participation of leading researchers in the field, the proceedings of this conference is a major reference work for graduate students and research workers in nuclear physics.

Download or read book Deep Inelastic Scattering Near the Coulomb Barrier written by and published by . This book was released on 1995 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep inelastic scattering was recently observed in heavy ion reactions at incident energies near and below the Coulomb barrier. Traditional models of this process are based on frictional forces and are designed to predict the features of deep inelastic processes at energies above the barrier. They cannot be applied at energies below the barrier where the nuclear overlap is small and friction is negligible. The presence of deep inelastic scattering at these energies requires a different explanation. The first observation of deep inelastic scattering near the barrier was in the systems {sup 124,112}Sn + {sup 58,64}Ni by Wolfs et al. We previously extended these measurements to the system 136Xe + 64Ni and currently measured the system 124Xe + 58Ni. We obtained better statistics, better mass and energy resolution, and more complete angular coverage in the Xe + Ni measurements. The cross sections and angular distributions are similar in all of the Sn + Ni and Xe + Ni systems. The data are currently being analyzed and compared with new theoretical calculations. They will be part of the thesis of J. Gehring.

This book was released on 1990-07-04 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of the harmonic oscillator with random frequency or/and random damping formed the content of the first edition. The second edition includes hundreds of publications on this subject since 2005. The noisy oscillator continues to be the subject of intensive studies in physics, chemistry, biology, and social sciences.The new and the latest type of a stochastic oscillator has also been considered, namely, an oscillator with random mass. Such model describes, among other phenomena, Brownian motion with adhesion, where the molecules of the surrounding medium not only randomly collide, but also stick to the Brownian particle for some (random) time, thereby changing its mass. This edition contains two new chapters, eight new sections and an expanded bibliography. A wide group of researchers, students and teachers will benefit from this book.

Book excerpt: Fusion reactions between different Kr and Ni isotopes were measured recently at ATLAS. We performed coupled-channels calculations and made comparisons to the measurements. Such calculations become increasingly difficult for heavy, soft nuclei due to strong couplings and the importance of higher-order, multi-step processes. The calculations were made possible by adopting the so-called rotating frame approximation, and they included one- and two-phonon excitations of the low-lying 2 and 3− states in both the projectile and the target. These calculations reproduced quite accurately the measured fusion cross sections for a beam of 86Kr. Some discrepancies remain for the much softer 78Kr nucleus; the calculations were clearly much more sensitive to higher-order processes in this case. In particular, it was important to implement the correct coupling strength and excitation energy for the soft, one- to two-phonon quadrupole transition in 78Kr, which differs significantly from the vibrational limit. This work was performed in collaboration with the experimentalists and was submitted for publication.
