4. FRIB Isotope Production Scheme Cartoon of the isotope production process at FRIB – projectile fragmentation or fission (Coulomb breakup, transfer, …) To produce a key drip line nucleus like 122 Zr the production cross section (from 136 Xe) is estimated to be 2x10 -18 b (2 attobarns, 2x10 -46 m 2 ) Nevertheless with a 136 Xe beam of 8x10 13 ion/s (400 kW at 200 MeV/u) a few atoms per week can be made and studied (>80% collection efficiency) For comparison: Element 117 production cross section was 1.3 (+1.5 -0.6) pb (1.3x10 -12 b) (Oganessian, Yu. Ts. et al PRL 104 (2010) 142502) Few x10 -46 m 2 is on the order of 100 MeV neutrino-electron elastic scattering cross sections projectile target Sherrill NN2012, Slide 4

21. Nuclear structure:  Model and accurately describe nuclei and their reactions.  For example, we want to develop the ability to calculate with sufficient precision reactions like 7 Be(p,  ) 8 B (responsible for source of neutrinos from the core of the Sun) from first principles. (e.g. Navratil, Roth, Quaglioni PLB 2011)  This goal is very relevant to many sciences and applications. Scientific Goals Sherrill NN2012, Slide 21

22.  Open questions What are the correct degrees of freedom to model nuclei? How do we model the nuclear force? How do we understand the nuclear force in terms of QCD? Are DFT approaches used in chemistry and advanced materials applicable?  Approaches (part historical, part current) Liquid Drop Model – scattering experiments show all nuclei have approximately the same density Bohr Hamiltonian (later IBM) – description of rotational and vibrational features of nuclei Independent particle models, Shell Model (based on effective interactions) Hartree-Fock (Bogoliubov) Effective potentials from 2-body scattering data  Experiments with rare isotopes over the past 10 years have demonstrated the problems with these approaches The Challenge of Modeling Atomic Nuclei Sherrill NN2012, Slide 22

23. Theory Roadmap – 2007 NSAC Long Range Plan  Step 1: Use ab initio theory and study of exotic nuclei to determine the interactions of nucleons in light nuclei and connect these to QCD by comparison to lattice calculations of NN and NNN forces (Fodor)  Step 2: For mid-mass nuclei use configuration space models. The degrees of freedom and interactions must be determined from exotic nuclei (Otsuka, Hagen, …)  Step 3: Use density functional theory to connect to heavy nuclei. Exotic nuclei help determine the form and parameters of the DFT. Toward Understanding the Nuclear Force Step 3 is the one that will answer the question about what are the heaviest elements.

24.  By measuring the differences we learn about the history of the star  The process that makes Barium (Ba) in early stars must be different from the main process that makes Iron (Fe)  There are many mysteries, only one example is that the [Ba/Fe] is not understood in early stars Chemical History of the Universe – the Fossil Evidence of the First Stars HERES Survey – Barklem et al.
