Shape coexistence and electric monopole transitions in atomic nuclei

23-27 October 2017 PROGRAM ESNTProjectShapesandE0_v3oct17.pdf

Organizers: E. Clément (GANIL), W. Korten (CEA Irfu, SPhN ) M. Zielinska (CEA Irfu, SPhN), T. Kibedi (Australian National University, Canberra), J. Wood (Georgia Institute of Technology, Atlanta).

The goals of the project are to:
1. review the available experimental data, both for nuclear ground state and for excited states, in several isotopic chains in which shape coexistence is observed, and identify benchmark cases for theory.
2. review the theoretical predictions for these benchmark cases and discuss possible new experimental approaches.
3. review progress in the detection of E0 decays (including long-lived isomeric states) and the theoretical progress to calculate E0 transition rates; explore the link between the low-energy electric monopole mode, nuclear cluster structure and the Giant Monopole Resonance.
4. identify any significant missing contributions both from the experimental and theoretical point of view.
