FUSTIPEN Topical Meeting
«Dipole collectivity in nuclei»
October 3-4, 2013, GANIL, Caen, France

Collective excitations of quantum many-body systems are characterized by the participation of many particles and often lead to an interpretation in terms of shapes. Besides the ubiquitous quadrupole-deformed states, nuclei may display dipole excitations associated with a linear displacement (or E1) mode, an angular displacement (or M1) mode, or even more complicated collective behaviour such as the shears mode. Many pertinent results, both experimental and theoretical, have been obtained over several decades.

We propose to organize a topical two-day meeting to discuss different types of dipole collectivity, to point out similarities and differences as compared to other quantum many-body systems, to suggest new experiments on nuclei, in particular to explore the dipole degree of freedom in the exotic realm where nuclei display an excess of nucleons of one type.
