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.
Heavy-ion Fusion: Exploring The Variety Of Nuclear Properties - Proceedings Of The Workshop
Inbunden, Engelska, 1994
2 071 kr
Tillfälligt slut
These proceedings review the present status and perspectives of research in this field which is currently of broad interest to the community of nuclear physicists.Many facets of fusion dynamics were discussed, ranging from energies well below the Coulomb barrier to higher energies. Various questions about compound nucleus decay were also addressed, and evidence of links between fusion, competing reactions and nuclear structures was presented: some talks concerned the superdeformed structures recently discovered in many nuclei. Part of the workshop was devoted to the fusion of very heavy systems, and to the production of superheavy elements. One session focused on fusion reactions with radioactive ion beams.
Perspectives For The Interacting Boson Model - Proceedings On The Occasion Of Its 20th Anniversary
Inbunden, Engelska, 1994
4 091 kr
Tillfälligt slut
These proceedings comprise the contents of a major international conference on Perspectives of the Interacting Boson Model. Occasioned by the 20th Anniversary of this model, and attended by approx. 130 scientists from 29 countries, the topics focused on current and future research, which relates to the IBM. This model has now become one of the standard approaches to nuclear structure and has helped usher in a renaissance in that field and a new, unified perspective that focuses on dynamical symmetries and the key role of the valence nucleons. The algebraic approach fostered by the model is being extended to other fields, including nuclear reactions, molecular physics and baryon structure.
Symmetries In Nuclear Structure: An Occasion To Celebrate The 60th Birthday Of Francesco Iachello - Proceedings Of The Highly Specialized Seminar
Inbunden, Engelska, 2004

Tillfälligt slut
The Highly Specialized Seminar on “Symmetries in Nuclear Structure”, held in Erice, Italy, in March 2003, celebrated the career and the remarkable achievements of Francesco Iachello, on the occasion of his 60th birthday. Since the development of the interacting boson model in the early 1970s, the ideas of Iachello have provided a variety of frameworks for understanding collective behaviour in nuclear structure, founded on the concepts of dynamical symmetries and spectrum-generating algebras. The original ideas, which were developed for the description of atomic nuclei, have now been successfully extended to cover spectroscopic behaviour in other fields, such as molecular or hadronic spectra. More recently, the suggestion by Iachello of critical point symmetries to treat nuclei in shape/phase transitional regions has opened an exciting new front for both theoreticians and experimentalists.The talks presented at the meeting covered many of the most active forefront areas of nuclear structure as well as other fields where ideas of symmetries are being explored. Topics in nuclear structure included extensive discussions on dynamical symmetries, critical point symmetries, phase transitions, statistical properties of nuclei, supersymmetry, mixed symmetry states, shears bands, pairing and clustering in nuclei, shape coexistence, exotic nuclei, dipole modes, and astrophysics, among others. In addition, important sessions focused on talks by European laboratory directors (or their representatives) outlining prospects for nuclear structure, and the application of symmetry ideas to molecular phenomena. Finally, a special lecture by Nobel laureate Alex Mueller, on s and d wave symmetry in superconductors, presented a unique insight into an allied field.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences
