Nucleon correlations
Using nuclear reaction and structure data to proceed to the drip lines
• Scientific question I
• Green‘s function method / framework
• DOM: data ⇒ self-energy / propagator data-driven extrapolations ⇒ drip line
• Outlook
• Scientific question II (some other time)
• Dynamic pion exchange
• (p,2p) in inverse kinematics ⇔ (e,e’p)

Nucleon correlations
Scientific Question I• How do the properties of protons and neutrons change as a
function of nucleon asymmetry?Properties: elastic p and n cross sections, bound single-particle properties, including removal energy, spectroscopic factors, strength distribution, one-body density matrix, E/A due to VNN.
Program• Employ framework of Green’s function method to link presently
available data to be cast in the form of the complex potentials (including their asymmetry dependence) that govern the behavior of nucleons in a large energy window: εF±200 MeV (or more) thereby linking (some) nuclear reactions with nuclear structure.
• Prediction of data for nuclei further along towards the dripline follows, allowing further improvements, etc.
Nucleon correlations
Description of the nuclear many-body problemIngredients: Nucleons interacting by “realistic interactions” Nonrelativistic many-body problemMethod: Green’s functions (Propagators) amplitudes instead of wave functions (efficient) keep track of all nucleons, including the high-momentum onesBook: Dimitri Van Neck & W.D. 2nd ed. 2008 Why: Physical insight and useful for all many-body systems Link between experiment and theory clear Can include all energy scales
Also available as a framework to analyze and interpret experimental data
