The second TALENT course on Theory for exploring nuclear reaction experiments will be given at the Facility for Rare Isotope Beams (FRIB) on the Michigan State University campus in East Lansing, MI from June 3 to 21, 2019. The principal lecturers will include Carl Brune, James DeBoer, Charlotte Elster, and Sofia Quaglioni.
As existing and upcoming radioactive ion beam facilities promise unprecedented access to a vast new array of exotic phenomena, reliable reaction theory is essential to establish a solid connection between measured reaction observables and the underlying nuclear structure, and ultimately to arrive at a complete understanding of nuclei and their role in the cosmos. Recent years have witnessed exciting progress in arriving at a more fundamental description of nuclear reactions, in which underlying many-body problem is solved exactly at small reaction energies using nuclear degrees of freedom. Once the energy becomes larger, many-body degrees of freedom proliferate while the reaction time often decreases (direct reactions). In those case it is more economic to concentrate on few relevant degrees of freedom and treat those exactly while projecting out most others.
While phenomenological approaches and standard approximated methods based on a few degrees of freedom continue to play an essential role in modeling nuclear reaction data, recent years have witnessed exciting progress in arriving at a more fundamental description of nuclear reactions. Many-body reaction methods rooted in the underlying theory of quantum chromodynamics are emerging and starting to describe reactions involving the lightest nuclei. Efforts are under way to forge connections between these more fundamental many-body descriptions and the phenomenological and direct reaction approaches.
Students participating in the course will be introduced to modern methods of describing nuclear reactions, develop an understanding of approximation methods employed in reducing the many-body reaction problem to a more manageable task, and will gain hands-on experience with describing nuclear reaction data. In particular, this advanced course will be focused on:
- Microscopic (or, calculable) and phenomenological R-matrix theory for the description of continuum scattering and reaction observables; and
- Coupled channels methods and other tools for interpreting direct reactions.
Deadline for applications is March 31, 2019.
