15 Overall Conclusions Phenomenological shell models, such as the Extreme Single Particle Shell Model (ESPM of Lecture 1) provide physical insight and guide our choices of theoretical paths Ab-initio NCSM is founded on this established physical intuition (Lecture 2) High precision comparisons between theory and experiment are emerging Applications up through A = 16 tell us that NNN interactions are needed with realistic local NN interactions New era of interplay between theory and experiment has emerged Outstanding Problems/Challenges (Sample) Role of NNN interactions with non-local NN interactions Converged saturation properties in better agreement with experiment RMS radius of 6-He not understood (discrepancy ~ 9%) Applications with NN + NNN potentials to reactions and scattering Applications to unstable light nuclei and to heavier (stable and unstable) nuclei Acknowledgment of material from many collaborations With thanks to many collaborators K.
