3. WG3: Timescale
Invitations late October/November - NuPECC Meeting March 11 and 12, 2016: Status report by NuPECC Liaison - NuPECC Meeting June 17 and 18, 2016: First draft and presentation by conveners - this implies that the draft is available before the meeting, i.e. beginning of June - NuPECC Meeting October 7 and 8, 2016: Final report, presentation by and discussion with conveners - this implies that the report is available before the meeting, i.e. end of September The six reports will then be put on the NuPECC Website together with the other chapters of the LRP and presented and discussed at an open Town Meeting at GSI Darmstadt; the tentative date for that is January 11 to 13, 2017.

6. SG1: Nuclear structure (key questions)
How are complex nuclei built from their basic constituents? What are the links to the underlying fundamental theory, QCD ?
What is the nuclear shell structure ?
a- What is the nuclear shell structure and what are the mechanisms of its evolution with proton-to-neutron ratios?
b- What are the limits of existence of nuclei (neutron and proton drip lines)?
c- Is there a “stabilization region” for very heavy elements?
What is the nature of in-medium two-nucleon and many-body correlations ?
How to explain collective phenomena from individual motion?
What is the nuclear matter distribution inside the nucleus ?
What are the properties of exotic nuclear systems?
Chaos and statistical description of the atomic nucleus
