Abstract:
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 Bürvenich 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. Readership: Graduate students, researchers and lecturers in nuclear physics.
