Proceedings Of The International Workshop Fission Dynamics Of Atomic Clusters And Nuclei

In this volume, the main results of the last sixty years of research in nuclear fission are summarized, showing how ideas advanced from the beginning, for nuclei have also found useful applications in the new area of atomic clusters. The present status of the physics of fission is discussed in depth, and perspectives for further research are outlined.

Following the pioneering discovery of alpha clustering and of molecular resonances, the field of nuclear clustering is today one of those domains of heavy-ion nuclear physics that faces the greatest challenges, yet also contains the greatest opportunities. After many summer schools and workshops, in particular over the last decade, the community of nuclear molecular physicists has decided to collaborate in producing a comprehensive collection of lectures and tutorial reviews covering the field. This third volume follows the successful Lect. Notes Phys. 818 (Vol. 1) and 848 (Vol. 2), and comprises six extensive lectures covering the following topics: - Gamma Rays and Molecular Structure - Faddeev Equation Approach for Three Cluster Nuclear Reactions - Tomography of the Cluster Structure of Light Nuclei Via Relativistic Dissociation - Clustering Effects Within the Dinuclear Model : From Light to Hyper-heavy Molecules in Dynamical Mean-field Approach - Clusterization in Ternary Fission - Clusters in Light Neutron-rich Isotopes By promoting new ideas and developments while retaining a pedagogical style of presentation throughout, these lectures will serve as both a reference and an advanced teaching manual for future courses and schools in the fields of nuclear physics and nuclear astrophysics.

The aim of the DANF conference was to present and discuss new theoretical and experimental results in the field of nuclear fission dynamics. The conference program was designed to cover a wide range of physical phenomena including spontaneous and induced fission at low and intermediate energies and fragmentation of hot nuclei. Among the topics discussed at the conference were: the development of various theories, experiments on the synthesis of superheavy elements, fusion-fission processes and the decay of complex nuclear systems, binary and ternary fission, nuclear structure of neutron-rich nuclei and the peculiarities of exotic nuclear reactions. Attention was also paid to the recent progress in developing radioactive ion beam facilities. The development of new methods was also on the conference agenda.

The Second International Conference on Atomic and Nuclear Clusters '93 was orga nized in a joint effort by the 'Demokritos' National Center for Scientific Research, G. S. Anagnostatos (representing the atomic physics) and the Hahn-Meitner-Institut, W. von Oertzen (representing the nuclear physics). The subject of clusters - small aggregates of particles - is a topic of primary interest in both atomic and nuclear physics, and also in other fields like in the case of quark-structure of baryons and in cosmology. The interplay between atomic and nuclear physics is a particularly fascinating one because many concepts are common to both fields (quantal effects, shells, geometric structures, collective modes, fission etc. ) This conference was the second after the first one organized by Professor M. Brenner in Abo (Finland) in 1991. The general atmosphere of a joint forum for atomic and nuclear physicists was very fruitful and thus the decision to have a sequence of such meetings has been taken. A third one is planned in St. Petersburg (Russia) with Professor K. Gridnev (St. Petersburg) and Mme. Professor C. Bnkhignac (Orsay) as Chairpersons. The conference site, Fin\. on Santorini island (Greece), was a wonderful choice for a conference. It is small, which helps to keep people concentrated in a smaller community, it has a perfect convention center, the P. Nomikos Conference Center, and a very beautiful landscape formed by a large volcanic crater.

This book deals with the properties and fusion dynamics of very heavy nuclei. It contains the latest experimental results on the formation and fission of superheavy nuclei and on the near-barrier fusion of light exotic nuclei, along with the different theoretical approaches to the description of fusion dynamics and microscopic properties of superheavy nuclei. The book also discusses nuclear collective dynamics and expectations from the use of accelerated beams of radioactive nuclei in fusion reactions. Contents: Aspects of Fusion, Fission and Cluster Radioactivity (W Greiner); Superheavy Nuclei in Deformed Mean-Field Calculations (T Brvenich et al.); The Synthesis of Superheavy Nuclei in the 48 Ca+ 244 Pu Reaction (Yu Ts Oganessian et al.); Fusion-Fission of Superheavy Nuclei at Low Excitation Energies (M G Itkis et al.); Semi-Bubbles and Bubbles: a New Kind of Superheavy Nuclei (K Dietrich); Reaction Theory for Synthesis of the Superheavy Elements (Y Abe); Fusion-Fission Dynamics of the Synthesis of Superheavy Nuclei (V I Zagrebaev); Sub-Barrier Fusion and Multi Nucleon Transfer in Medium-Heavy Nuclei (F Scarlassara et al.); Mechanisms of Sub-Barrier Fusion Enhancement (N Rowley); Transfer, Breakup, and Fusion Reactions of 6 He with 209 Bi Near the Coulomb Barrier (J J Kolata); Study of Sub-Barrier and Near-Barrier Fusion of Halo Nuclei (N Alamanos et al.); and other papers.
