Room: Lecture Hall (KBW) Additional suggestions or material (for example one or two slides) presented which may be used to generate topics of interest. For example, general topics may include (please suggest your topic / contribution in advance): • Production of 229Th/ 229mTh at on-line accelerator facilities (e.g. GSI, Jyväskylä,…) • Off-line production/sources of 229Th • Low-energy isomers (in addition to 229Th), quest for alternative candidates • Open questions in theory (Atomic Physics, Nuclear Physics, the interface between both) • New collaborations, student exchange • Mechanisms for funding
