Three-nucleon interactions and two-body electroweak current operators are important additional inputs. Present variational and Green's function Monte Carlo methods allow us to study nuclei up to A=12 with unprecedented accuracy. Properties we can evaluate include binding and excitation energies and the relative stability of neighboring nuclei. We can also study fine details like charge-independence-breaking and isospin-mixing, one- and two-nucleon densities in configuration and momentum space, electromagnetic moments and electroweak transitions, and nucleon-nucleus scattering. Overall, we have made great progress in understanding how complicated aspects of nuclear structure arise from the pairwise interactions between individual nucleons.</p> <p align="center"> </p> <p align="center"> Presentation: OCNPS 200 @ 3:00 pm</p> <p align="center"> Refreshments: Atrium @ 2:30 pm</p> <p align="center"> More details at <a href="http://sci.odu.edu/physics/">http://sci.odu.edu/physics/</a></p> <p align="center"> All are Welcome!</p> <p> </p>
